Service level: BAN_MEMBERS refusal (Forbidden even for nonexistent targets
— no id enumeration), equal-rank and owner-target hierarchy refusals,
authorized ban/unban round-trip, self-ban rejection. Admin API level:
equal-rank owner ban 403s, a lower-positioned ADMINISTRATOR cannot ban the
owner, downward bans still work. All existing NewAdminAPI/NewHandler test
callsites now inject a real ModerationService so the production
authorization runs in every PATCH-user test.

Critical fixes:
- Move svc creation in router.go above MountInviteRoutes/MountChannelRoutes
(was used before definition — compile error)
- Restore hasChannelPermREST in channel_handler.go for upload_handler.go
(was removed but still referenced — compile error)
Permission cache invalidation:
- Add PermissionInvalidator interface to admin package
- Wire through NewHandler → NewAdminAPI → handlePatchUser
- Call InvalidateUser(userID) after role changes in admin panel
- Update all admin test files to pass nil as new parameter
Also clarifies WithTx documentation for SQLite single-writer semantics.

Replace separate UserCount() + CreateUser() with atomic
CreateOwnerIfEmpty() that checks and inserts in a single SQLite
transaction. Concurrent race test validates exactly 1 owner under
20 parallel requests.
The first-run setup POST was vulnerable to cross-site request forgery
because it had no Origin validation. Added isSetupOriginAllowed check
that validates the Origin header against configured allowed_origins.
Requests with a mismatched Origin are rejected with 403. Requests
without an Origin header (same-origin or curl) are allowed through.
- C-3: inject setupLimiter into NewAdminAPI instead of package-level global
- H-5: generateRandomKey returns error instead of panicking
- H-6: replace init() bcrypt with sync.Once lazy initialization
- M-2: remove unsafe-inline from admin CSP script-src and style-src
- M-3: sanitize upload filenames (strip control chars, truncate to 255)
- M-5: truncate User-Agent to 512 bytes before storing as device
- M-10: MaxBodySizeUnless uses prefix matching instead of exact path
- M-12: wrap seedExistingDatabase in a single transaction
- M-13: use errors.Is for EOF check in upload handler
- M-14: log writeJSON encoding errors instead of discarding
- M-16: standardize error codes to INTERNAL_ERROR across all handlers
Admin panel redesign:
- Rebuild frontend from mockup with Discord-style dark theme
- Stat cards, section cards, role badges, modal system, toast notifications
- All 7 sections: Dashboard, Users, Channels, Audit Log, Settings, Backups, Updates
- Modals replace confirm()/prompt() for all destructive actions
Live server logs (new):
- RingBuffer + MultiHandler tees slog to stdout AND in-memory buffer
- SSE endpoint at /admin/api/logs/stream streams logs in real-time
- Log viewer with level filters (DEBUG/INFO/WARN/ERROR), search,
auto-scroll, pause/resume, copy all, clear
- Color-coded lines by level, source categorization from file paths
Audit log improvements:
- Search filter (actor, action, target, detail)
- Action type dropdown filter
- Copy All and Export CSV buttons
- Instant client-side re-filtering
Console output:
- Switch from JSON to human-readable text format (slog.TextHandler)
- Move startup banner before init logs so it appears first
When no users exist, the admin panel shows a setup wizard instead of the
login form. Creates the first Owner account with a session token and
generates an unlimited invite code for onboarding other users. The setup
endpoint is locked out after the first user is created.
Also fixes the admin panel 404 by serving index.html directly for the
root path instead of delegating to http.FileServer.
