Replaces the basic credential-pill quick-switch with a Manage-Workers-styled
modal (topbar + left rail + panel, entrance animation, brand-logo cards).
- Sidebar Service Status: whole panel opens the modal; clicking the Metadata /
Media Server / Download rows deep-links straight to that tab. Removed the
"switch ▸" hover text.
- Three tabs: Metadata (source logo cards, unavailable ones dimmed), Server
(Plex/Jellyfin/Navidrome/SoulSync logos), Download (Single⇄Hybrid segmented
toggle; Hybrid shows a draggable priority list). Logos reuse SOURCE_LABELS +
HYBRID_SOURCES; active card gets an accent ring + check.
- Admin writes the GLOBAL active source/server/download (reuses the same setters
+ client reloads as the Settings save, so changes take effect immediately).
Non-admins see it read-only (editable=false) — the per-profile override is the
next layer.
Backend: GET /api/profiles/me/active-sources (any profile; reports editable),
POST /api/profiles/active-sources (@admin_only; validates against the allowed
metadata/server/download lists, applies + reloads). New service-switch.js
(registered + in the integrity registry); old modal removed from
credential-sets.js (admin Connected Accounts manager stays).
Tests: 14 endpoint tests — read shape, admin sets metadata/hybrid+order
(reflected), bad-value 400s, non-admin read-only + 403 on write. 64 integrity
tests pass; real-app smoke confirms render + deep-links + the full set/reflect
cycle.
