feat(dedicated): build summary sidebar + expanded CPU/IPv4 options

CPU upgrade ladder (standard, R440/R540/R640/R740) now 6 tiers:
- Gold 6230 (baseline, included)
- Gold 6244 high-clock (16C / 3.6 GHz, +$25/mo) — for per-core
  licensed workloads (MS SQL / Oracle) and single-threaded compute
- Gold 6248 (40C / 2.5 GHz, +$35/mo)
- Gold 6230R sweet-spot (52C / 2.1 GHz, +$50/mo) — Cascade Lake
  Refresh of the 6230, more cores at same clock, bridges baseline
  and 6248R
- Gold 6248R (48C / 3.0 GHz, +$75/mo)
- Gold 6258R (56C / 2.7 GHz, +$145/mo)

R740xd CPU ladder unchanged (6230 / 6248R / 6258R / Platinum 8280).

IPv4 block options extended to /24:
- /29 ($12) · /28 ($36) · /27 ($80) · /26 ($145) · /25 ($275) ·
  /24 ($499). All blocks above /29 require ARIN justification —
  the group description explains the policy and each tier's label
  carries a "justification required" tag.

Build summary sidebar replaces the bottom sticky footer on the
per-chassis page. New 2-column layout (configurator left, summary
right, sticky); collapses to single-column on tablet/mobile with
the summary stacked above the configurator so total stays visible.

The summary fixes the original "Total $468 billed monthly /
includes $349 setup" wording confusion by splitting into clearly
labeled sections:
- RECURRING: per-line itemized breakdown (baseline + each upgrade
  with its actual cycle-priced cost), subtotal in /mo or /yr suffix
- ONE-TIME: setup fee with non-refundable note (or strikethrough +
  "waived" badge when cycle is semi/annual)
- TOTAL: "First invoice $X" + "Then $Y/mo recurring" framing on
  monthly/quarterly cycles; "Total due today" + renewal preview on
  semi/annual

Removed: ConfiguratorFooter.vue (replaced by BuildSummary).
Pinned to top via position:sticky with viewport-height clamp +
internal scroll for tall configs. Order CTA + Copy share link
moved into the summary card.
