Audit writes stay best-effort — a LogAudit failure must never fail or abort
the request — but a failed write must no longer be silently discarded. Add
db.WriteAudit(auditor, actor, action, targetType, targetID, detail), which
logs a failed write with actor/action/target context (never the detail
string, which may be sensitive) and never propagates the error.
The Auditor interface is satisfied structurally by both *db.DB and the
service-layer Store, so api/admin/ws/service all reach the helper without an
import cycle. Converts all ~26 call sites from `_ = LogAudit(...)` (and the
two backup handlers' inline `if err` blocks) to db.WriteAudit. Pinned by
db/audit_test.go: failure logged and not propagated, success logs nothing,
detail never leaks.
Resolves the repo-wide LogAudit policy question flagged by the D8 note.

contextcheck (CI lint) flagged the admin handler calling BanUser without
the request context — the service opened its telemetry span from
context.Background(), detaching the ban from its request trace. Both
moderation entrypoints now take ctx; the span joins the caller's trace.

requireBanAuthority (BAN_MEMBERS + role hierarchy) was wired only into
ModerationService.BanUser/UnbanUser — which had zero production callers.
The live path, handlePatchUser, ran a raw UPDATE with no hierarchy check,
so any admin-panel actor could ban an equal- or higher-ranked user,
including the owner. The ban/unban branch now calls the service (dead code
becomes THE code — ban path 1 of 3 consolidated), which also audits as
user_ban/user_unban, keeping the historical audit vocabulary.
Authorization now runs in permission → existence → hierarchy order: an
actor without ban authority sees Forbidden, never NotFound, so the ban
path cannot enumerate user ids. The role+ban transaction is gone — the
ban leg lives in the service, runs first, and a refusal returns before
the role change executes, so a rejected ban never half-applies a PATCH.
MemStore gains honest BanUser/UnbanUser so the matrix is testable.

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.
