Deluan Quintão 11640f2e4d fix: restrict transcoding config reads to admins (#5564)
* fix(security): restrict transcoding config reads to admins

Authenticated non-admin users could read transcoding configs through
the native API (GET /api/transcoding and /api/transcoding/{id}) when
EnableTranscodingConfig was enabled. The responses included the full
command templates, disclosing admin-configured ffmpeg invocations and
local command paths. Write operations were already admin-only.

The /transcoding route was registered in the general authenticated
group, and only the repository's write methods checked IsAdmin. This
applies the boundary at two layers:

- Move the route under adminOnlyMiddleware, alongside the other
  admin-only resources (/library, /config, /inspect).
- Add an IsAdmin guard to the repository's rest.Repository read
  methods (Read, ReadAll, Count) as defense-in-depth.

The guard is scoped to the REST methods only. The streaming pipeline
resolves profiles via Get/FindByFormat (model.TranscodingRepository),
which stay open so transcoding keeps working for non-admin users.

Adds regression tests covering non-admin read denial and confirming
non-admin streaming lookups (Get/FindByFormat) still succeed.

* fix(security): redact transcoding Command for non-admins instead of blocking reads

Reworks the previous approach after review (Codex P2): moving /transcoding
under adminOnlyMiddleware and denying non-admin reads broke legitimate
non-admin UI flows. The web UI reads the transcoding resource as a regular
user in several places that need only the profile name and target format:
the player edit dropdown (ReferenceInput), the player list (ReferenceField),
and the share/download format pickers (useGetList -> {targetFormat, name}).

The only sensitive field is Command (the admin-owned ffmpeg template). So:

- Revert the route move; /transcoding stays in the authenticated group.
- Read/ReadAll now return the profiles to any authenticated user but blank
  the Command field for non-admins (mirrors user_repository's field-level
  redaction). Count is no longer denied (the UI needs list pagination).
- Writes remain admin-only (Save/Update/Delete/Put).
- Streaming is unaffected: it resolves profiles via Get/FindByFormat, which
  are not redacted, so on-the-fly transcoding keeps working for non-admins.

Tests updated: non-admin reads succeed with Command blank, admin reads keep
Command, non-admin Get/FindByFormat keep Command, writes still denied.
