nesquena-hermesandweidzhou 3fde698232 fix(sessions): always retry sidebar session-list GET on 502/503/504 (#5394)
The sidebar session-list GET had 502/503/504 retry logic, but it was gated
to cold boot only. Once `_sessionListHasLoadedOnce` flipped true, every later
refresh (profile switch, focus/visible/reconnect) shipped no retryStatuses, so
a transient 502 during an nginx->backend restart window failed on the first
attempt and left the sidebar stale until a hard reload (Ctrl+F5).

The session-list GET is idempotent, so retrying it is safe unconditionally.
This moves `retries:1` + `retryStatuses:[502,503,504]` into the base request
options so they apply to every refresh, while keeping the larger boot timeout
(`_SESSION_LIST_BOOT_TIMEOUT_MS`) and `retryTimeouts` boot-only. The api()
wrapper in static/workspace.js already retries when the error status is in
retryStatuses, so no other change is needed.

Extends the existing source-string regression test to assert the retry
options are now always present (declared before the boot-only gate) while the
boot path still carries the timeout + timeout retry.

Reported and root-caused by @weidzhou, who traced the boot-only retry gate.
