## Problem
Two separate code paths refreshed chat diff statuses:
1. **HTTP handler** (`refreshChatDiffStatus`): resolved
provider/token/status inline, ran under the user's context. Worked fine
because the user owns their external auth links.
2. **Background worker** (`Refresher.Refresh`): ran under `AsChatd`
context, which lacked `ActionReadPersonal` on `ResourceUser`.
`GetExternalAuthLink` failed silently (`if err != nil { continue }`),
returning `ErrNoTokenAvailable` every time. Chat diff statuses got
`git_branch`/`git_remote_origin` from `MarkStale` but `refreshed_at`,
`url`, `pull_request_state` stayed nil.
Having two paths also meant bug fixes had to be applied twice.
## Fix
- **`Worker.RefreshChat`**: New method for synchronous, on-demand
refresh of a single chat. Uses the same `Refresher.Refresh` pipeline as
the background `tick()`. Called by the HTTP handler for instant
response.
- **`resolveChatGitAccessToken`**: Uses
`dbauthz.AsSystemRestricted(ctx)` specifically for `GetExternalAuthLink`
and `RefreshToken` calls. This is scoped to just those DB operations
rather than broadening the chatd RBAC role.
- **Removed**: `refreshChatDiffStatus`, `shouldRefreshChatDiffStatus`,
`resolveChatDiffStatusWithOptions` (all replaced by the single
`RefreshChat` path).
## Tests
Added 4 tests for `Worker.RefreshChat`:
- `TestRefreshChat_Success`: full refresh + upsert + publish
- `TestRefreshChat_NoPR`: no PR exists yet, nil result
- `TestRefreshChat_RefreshError`: provider resolution fails
- `TestRefreshChat_UpsertError`: refresh succeeds but DB write fails
## Why tests didn't catch the original bug
- Worker tests used mock stores (no dbauthz) and fake token resolvers
(hardcoded lambdas)
- No integration test exercised `AsChatd` -> `resolveChatGitAccessToken`
-> `GetExternalAuthLink` through dbauthz
