Claude 7c3e4b8a38 fix(api-v3): address CodeRabbit findings on the blueprint split
- _redact_credentials: blank scalar descendants of objects reached
  through a credential-owned list (e.g. tokens: [{"value": "secret"}])
  regardless of field name -- the existing name-based walk only
  protected direct dict values under a credential key, not list items.
- wifi.py: reject enabled/force/auto_enable_ap_mode values
  _parse_bool_ish can't recognize (400) instead of silently treating
  them as False, which could disable Wi-Fi or the radio itself.
- Starlark manifest locking: lock a stable manifest.json.lock sidecar
  instead of manifest.json itself, in both the standalone route path
  (_starlark_manifest_lock) and the plugin path
  (StarlarkAppsPlugin._save_manifest / _update_manifest_safe).
  manifest.json is replaced by an atomic rename on every write, which
  swaps in a fresh inode; a lock held on the old inode does not
  exclude a second locker that opens the path afresh right after the
  rename and gets the new inode, so two writers could race despite
  each holding "a lock". A sidecar that no write ever touches always
  resolves to the same inode for every locker.

Skipped as stale: the "serialize the complete manifest
read-modify-write" finding at api_v3/__init__.py -- every standalone
handler that calls _write_starlark_manifest is already wrapped in
_starlark_manifest_lock() on this branch.

"""
Endpoint tests for the /wifi/* routes in api_v3.
These routes drive the host's actual networking — connecting, dropping a
connection, switching the radio off — and had no endpoint-level tests at
all. WiFiManager is mocked throughout; nothing here may touch real
networking.
Each handler does `from src.wifi_manager import WiFiManager` inside the
function body, so the patch target is the class at its definition site.
