🚀 XC_VM v2.5.0

A major modernization release. The administration and reseller panels have been
rebuilt on Bootstrap 5 with JSON-driven tables, modal/tabbed forms, a new
dashboard and navigation — alongside continued streaming, module and update
system improvements.

✨ Highlights

• Complete Bootstrap 5 admin UI migration — new shell, layout, navigation,
  dashboard, tables, forms and modals.
• JSON-driven management tables replacing the legacy positional-column
  rendering, with client-side rendering, filters, live refresh and bulk actions.
• New dashboard with statistics cards, live stats and a world map of active
  connections.
• Global quick search in the admin header, with results rendered as cards.
• Reseller panel migrated to the same Bootstrap 5 UI.
• Redesigned admin & reseller login as a sci-fi HUD interface.
• Per-user UI customization persisted in users.ui_prefs.

🎨 Admin UI (Bootstrap 5)

• New per-page opt-in admin shell and a Bootstrap 5 v10.11.1 asset kit; assets
  split into old/new and later flattened, dropping the legacy tree.
• Shared per-page topbar (JSON-driven), reorganized sidebar into a cleaner
  information architecture, and a Content split into Streaming / VOD /
  Distribution tabs.
• Management tables migrated to clean-JSON endpoints: Live Streams, VOD/Movies,
  TV Series & Episodes, Users/Resellers, MAG & Enigma2 devices, Radio Stations,
  Servers & Proxy Servers, Lines & Live Connections, EPG, Backups, Packages/
  Groups/Codes/Providers, Blocked IPs/ISPs/ASNs/User-Agents/HMACs/RTMP IPs,
  Created Channels, Tickets, Transcoding Profiles, On-Demand Scanner, VOD Theft,
  Stream Rank, Encoding Queue, and the log tables (Panel Errors, Login, Client,
  Credit, Reseller, Activity, Stream Errors, Restream, MAG Events, System).
• Edit forms rebuilt as Bootstrap 5 modals / tabbed layouts: live streams,
  movies, series, episodes, radios, MAG & Enigma2 devices, lines, users
  (resellers), packages/groups/codes/providers, HMAC, EPG, bouquets, proxy,
  servers, transcode profiles, fingerprint, and the *_mass bulk-edit forms.
• Live table auto-refresh (soft-live: only changed rows re-render, paused on an
  open dropdown), modal delete confirmations, in-table player previews, and
  select2 owner/bouquet/package pickers.
• Replaced native alert() dialogs with a shared xcToast notification.
• Fixed navigation labels and expanded i18n coverage.

📊 Dashboard

• Rebuilt on Bootstrap 5 with statistics cards and page-prefixed i18n.
• Added a connections world map (jsvectormap) and redesigned server cards
  with sparklines.
• Live statistics with polling reduced from 1s to 5s.
• Live per-user interface customizer persisted to users.ui_prefs.
• Added a dedicated Home dashboard nav item.

🔧 Modules & Updates

• Added module provider contracts for topbar, tables, permissions and quick
  tools; moved those concerns out of core into dedicated providers.
• Added per-repository update channels (Stable/Beta) for the panel, binaries
  and the xc_fanout daemon.
• Improved GeoIP release synchronization: GitHubReleases is now a generic
  release client, with GeoLite2/GeoIP2-ISP sync owned by the domain layer and
  the ISP database updated through the same path as GeoLite2.

🎬 Streaming & Fanout

• Added a panel setting to configure the xc_fanout source backend
  (auto / ffmpeg / native).
• Added xc_fanout version tracking (sidecar file) and integrity probing.
• Kept HLS MEDIA-SEQUENCE monotonic across off-air ↔ live transitions.
• Reworked the admin stream entry points (live/vod/timeshift/thumb) for
  readability and testability, and fixed a segment retry-budget precedence bug
  and a stats division-by-zero.

🛠 Fixes

• Fixed cron:vod aborting on degenerate ffprobe output under PHP 8.
• Fixed load-balancer installation on Ubuntu 24.04 / Debian 13 (missing curl)
  and made binary release resolution resilient to GitHub API rate limits.
• Surfaced server install status and allowed deleting offline servers.
• Wired the Panel Errors page actions to the topbar.
• Fixed assorted admin-UI issues: episodes topbar, DataTable header alignment,
  row-action dropdown clipping, responsive child-row alignment, form UX.
• Fixed various PHP 8 compatibility and null-safety issues.

🧰 Tools & Testing

• Added a synthetic test pattern to the stream generator — test streams
  without an input file (stopwatch/clock overlay, hardened for long runs).
• Merged the stream checker and grapher into a single stream_check.py.
• Added a Playwright end-to-end smoke harness and suite for the migrated
  Bootstrap 5 admin.

📚 Documentation & Maintenance

• Rewrote the contributor guide; documented module provider contracts and the
  controller/REST wiring.
• Updated FFmpeg documentation and ADRs.
• Removed obsolete DTS/AC3 testing helpers.
• Updated dependencies, including PHPStan.
