fix(ppsk sync): match by name + salvage settings, prune dup tombstones

Every rotation changes an embedded PPSK's synthetic id (it's derived
from sha256(wlan_id : passphrase)). The ingest sync matched only by
unifi_id, so after rotation the row's id was "new" — the sync created
a fresh active row and marked the previous one held. Over multiple
rotations this accumulated: each rotation left a held tombstone, and
the rotate_password / schedule flags were stuck on the original
tombstone instead of transferring to the new active row.

Dev's GUEST PPSK had 3 rows after a few rotations: two held (with
rotate_password=true on the first), one active with rotate=false.
Future rotations would silently skip that PPSK because the active row
no longer had the rotate flag set.

Fix in three layers, all in WifiController::ppskIndex:

1. Match priority extended: unifi_id → name within wlan → held by
   passphrase. The name match means a passphrase change just updates
   the existing row in place. No more new-row creation per rotation.

2. Salvage step before pruning: for each active row, scan held
   tombstones with the same name and copy over rotate_password and
   schedule. Operator's rotation opt-in survives history.

3. Prune step: held rows with the same name as an active row in the
   same wlan are now hard-deleted (their settings were just salvaged,
   their data is stale). Keeps the WiFi modal clean instead of
   accumulating phantoms.
