Some checks failed
Publish Release / release (push) Failing after 16s
chore(release): 1.5.0
Major client-area overhaul, WHMCS 9 + VirtFusion v7 compatibility, and a
hardening pass on every destructive client.php endpoint.

Tested against WHMCS 9.0.3 + VirtFusion v7.0.0 Build 9.

Features
- "On This Page" jump-link group injected into the WHMCS Actions sidebar
  via ClientAreaPrimarySidebar; auto-hides links for hidden panels.
- Monthly traffic chart (last 12 months) with rx/tx bars and centered
  legend; replaces the dead canvas that read non-existent JSON paths.
- Live Stats panel: CPU, memory, disk I/O from remoteState; 30s refresh
  while the panel is visible AND the page has focus.
- Filesystem usage rows in the Resources panel from qemu-guest-agent
  fsinfo; pseudo-FS filtered out.
- Server Overview meta chips: data-center location with country flag,
  OS template/agent name with kernel on hover, "Created N days ago".
- Hypervisor maintenance banner at the top of the page.
- Mask Sensitive screenshot mode: IPv4 keeps first two octets, IPv6
  keeps first two hextets, hostnames keep first char per dot-label.
  Inputs masked via text-security: disc; covers Server Name + Hostname
  + IP cells + rDNS panel rows.
- Per-IP copy buttons folded into the Server Overview cells (replaces
  the deleted standalone Network panel).
- VNC viewer popup served from a same-origin authenticated route
  (client.php?action=vncViewer) — POST + requireSameOrigin, rotates
  the wss token on every open, X-Frame-Options DENY, strict CSP.

Bug Fixes
- UsageUpdate cron silently no-op'd: read server.usage.traffic.used
  which doesn't exist. Bandwidth now from /servers/{id}/traffic;
  disk usage from remoteState.agent.fsinfo.
- WHMCS 9 multi-service order short-circuit: AfterModuleCreate's
  AcceptOrder fired after the first service and terminated the batch
  loop, orphaning siblings. Defer until every VF service in the order
  has a server_id.
- Orphaned services produced six generic 500s; new
  requireProvisionedService() helper emits one clean 409 with an
  actionable message. Wired into all 17 client.php cases.
- Server Overview Traffic showed "- / Unlimited"; now renders real
  bytes and "Unmetered" (limit=0 is per-period uncapped, not feature-off).
- Rename endpoint moved to PUT /servers/{id}/modify/name in VF v7
  (was 404'ing); response is HTTP 201 not 200/204.
- Rename was force-lowercasing the input; relaxed validation to
  preserve case + freeze the input row mid-flight to prevent
  double-submits.
- "Other" OS category icon override removed; uses VirtFusion's icon
  instead of a hardcoded SVG.
- Save button squish on the rename row fixed via flex-wrap layout.

Security
- CSRF protection (requirePost + requireSameOrigin) added to every
  destructive POST: rebuild, resetPassword, resetServerPassword,
  powerAction, rename, selfServiceAddCredit, toggleVnc, vncViewer.
  Previously only rdnsUpdate had it.
- Open-redirect defence in Module::fetchLoginTokens — refuses to
  return a redirect URL whose host doesn't match the configured VF
  panel hostname.
- Per-action rate limiting via new Module::requireRateLimit helper
  (Cache-backed): rebuild 60s, resetPassword/resetServerPassword 30s,
  powerAction 10s, vncViewer/toggleVnc/selfServiceAddCredit 5s.
- vncViewer route delivers strict Content-Security-Policy
  (default-src none, script-src self + VF panel, connect-src wss VF
  panel, frame-ancestors none).
- IPv6 examples in placeholder/comments switched to the IANA
  documentation prefix 2001:db8::/32 (RFC 3849).

Removed
- Network panel (duplicated Server Overview IP rows).
- VNC enable/disable toggle (VF firewall flag is non-functional;
  toggle was misleading).
- Network Speed row in Resources panel (always 0 from VF API).

Internal
- Module::fetchServerData now passes ?remoteState=true.
- ServerResource::process exposes osName/osPretty/osKernel/osDistro/
  osIcon/location/locationIcon/hypervisorMaintenance/createdAt/
  builtAt/live.* fields.
- Module::toggleVnc corrected to send {vnc:bool} (the actual API
  param) instead of {enabled:bool} (silent no-op).
- Module::getVncConsole + toggleVnc return baseUrl alongside the
  envelope so the viewer route can build the wss URL.
- Panel margins tightened mb-3 → mb-2 across all 11 panels.

/**
* Client-facing AJAX API endpoint.
*
* ROUTING MODEL
* -------------
* Every request carries ?action=X&serviceID=Y. We dispatch on $action via the
* switch below. Because PHP's switch() is O(N) over case labels that's still
* fine at ~20 actions; if this grows large enough that dispatch cost matters
* we'd want a lookup table, but we're nowhere near that.
*
* WHMCS requires every action URL to re-authenticate on each request (no
* cross-request sticky state beyond the session cookie). That's why the
* isAuthenticated() call is the first thing inside the try block — nothing
* downstream may assume a session exists.
*
* AUTH LAYERS (ORDER MATTERS)
* ---------------------------
* Each case composes the defenses it needs:
*
* 1. $vf->isAuthenticated() — client session (401 otherwise)
* 2. $vf->validateServiceID(true) — numeric coercion + presence
* 3. $vf->validateUserOwnsService($id) — the session owns this service (403)
* 4. Optional: requireServiceStatus — filter by tblhosting.domainstatus
* 5. Optional (mutations): requirePost — HTTP method gate (405)
* 6. Optional (mutations): requireSameOrigin — CSRF origin gate (403)
*
* The helpers are "fail loudly" — they exit on failure rather than returning.
* So everything AFTER a guard in a case branch knows the guard passed.
*
* EVERY $vf->output() FOLLOWED BY break
* -------------------------------------
* output() emits a JSON response and exits by default, so in theory `break`
* is redundant. In practice we always break explicitly for two reasons:
* 1. If someone later passes exit=false to output() the switch would fall
* through to the default case and emit a second response body.
* 2. Code readers shouldn't have to remember that one function exits.
*
* RESPONSE SHAPE
* --------------
* Success: { success: true, data: { ... } }
* Error: { success: false, errors: "human-readable message" }
* Status codes match HTTP semantics (200/400/401/403/404/405/429/500/502).
*
* CATCH-ALL
* ---------
* The outer try/catch guarantees we never expose a raw PHP stack trace to the
* client, even on bugs in our own code. All uncaught exceptions are logged and
* the user sees a generic 500.

* uses:
* - WHMCS session required (isAuthenticated)
* - validateUserOwnsService prevents cross-customer access
* (any other customer hitting this URL with their session
* gets a 403)
* - requireProvisionedService blocks orphan services
*
* Each request rotates the wss token by POSTing to VirtFusion's
* /vnc endpoint with vnc:true — older tokens VirtFusion was
* tracking are superseded, so a leaked token from a previous
* popup open is no longer usable after the next click.
*
* Method is POST (not GET) so we can require same-origin and
* avoid the GET-with-side-effects anti-pattern. JS opens the
* popup via a hidden form-submit (see vfOpenVnc in module.js).
