fix(banded ssid): match embedded PPSK by name first, passphrase fallback

Browse Source 
The sibling-update path on prod failed with "Embedded PPSK not found
by current passphrase" because the DB-stored x_passphrase on the
unedited band was stale — earlier manual edits (pre-1.8.1) only
touched one band, leaving the other band's row out of sync. When
rotation then tried to use that stale passphrase to find the entry,
no match.

updateEmbeddedPpsk now takes an optional $name parameter and tries it
first. PPSK names within a WLAN are unique, so name-matching survives
any passphrase drift caused by historical out-of-band edits.
Passphrase matching stays as a fallback for callers that don't have
a name (none currently — both rotation and the manual modal pass it).

v1.9.1.
