Wires the auto_approve_requests user flag into the request creation
flow. When the flag is set (admin enabled it via /admin/users from
U2-T3), POST /api/requests transitions the just-created pending row
through Service.Approve inline, which dispatches to Lidarr the same
way a manual admin approve does.
Failures inside Approve (ErrLidarrDisabled, ErrDefaultsIncomplete,
network/Lidarr errors) leave the row pending — same fallback as
manual approve hitting the same path. The user gets a 201 either
way; admin can still resolve the row in /admin/requests if it
stayed pending. The handler logs the auto-approve failure with
user_id + request_id for observability.
The "actor" id passed to Approve is the user's own ID — they're
acting under the privilege the admin granted them via the toggle.
The trail of "admin set the flag" already lives in audit_log
(ActionAutoApproveToggle from U2-T2). Adding a per-auto-approval
audit entry is a future enhancement; for v1 the toggle audit plus
the request row's status transition is enough.
Test verifies the Lidarr-disabled fallback contract: a user with
auto_approve=true and Lidarr unavailable still gets 201 Created
with status=pending (no crash, no 500). The "auto-approve actually
succeeds" test path requires a Lidarr stub; deferred until a
broader Lidarr test fixture lands.
Implements POST/GET/GET:id/DELETE /api/requests handlers delegating to
lidarrrequests.Service; wires routes in RequireUser group and threads
the service through Mount and server.go.
