Add email integration for ticket system and IMAP inbound support

Email integration: IMAP polling via webklex/php-imap (M365/Zoho/MIAB
compatible), TicketEmailProcessor with 3-strategy ticket matching
(In-Reply-To, References, subject line [EZSCALE-{id}]), signature and
quote stripping, scheduled command every 2min.

Outbound: 4 notification classes (TicketCreated, CustomerReply,
StaffReply, StatusChanged) with email threading headers via
withSymfonyMessage(). Staff replies set Reply-To: support@ezscale.cloud.

Frontend: ticket reference chips on all pages, "Via Email" badges on
email-originated replies. 12 new tests (163 total, 816 assertions).
