PR #11036 added a per-request permission check to the file-media asset
endpoints (/assets/by-file-media-id/:id and the /thumbnail variant) using
bfc/get-file-permissions. Anonymous share-link viewers were then rejected
because they have neither a session nor an access token, the asset URL
carries no share context, and the 2-arg get-file-permissions short-circuits
to nil when profile-id is nil.
Make the asset endpoints share-link aware, mirroring how get-view-only-bundle
already authorizes the same scenario: read the share-id from the query
string, validate it as a UUID, and call the 3-arg perms/get-file-read-permissions
(which chains the existing 2-arg bfc lookup, the bfc share-link fallback,
and the Nitrate org-owner fallback). On the frontend, extend
cf/resolve-file-media with an optional share-id arg and pass it from the
WASM viewer render path using the share-id already present in
[:viewer-local :share-id]. Non-viewer call sites (workspace, clipboard,
code-gen) keep the original URL shape because the new arg defaults to nil.
Closes#11338

Add authorization check to generic-handler in assets.clj so that
/assets/by-file-media-id/:id and its /thumbnail variant verify the
requesting profile has read access to the parent file. Return 404
(not 403) when access is denied to avoid confirming existence.
Also switch get-file-media-object from db/get to db/get* so that
non-existent media objects return nil instead of raising.

- Add ::setup/props and ::db/pool to :app.http.assets/routes config
so session renewal works correctly for asset requests.
- Add actoken/authz middleware to the assets middleware chain so
access tokens are properly recognized.
- Add authenticated? helper that checks both ::session/profile-id
and ::actoken/profile-id, fixing 401 errors when accessing
protected assets with a valid access token.
- Add comprehensive test suite for assets auth scenarios.
Closes#9677
