Storing the verification phone as a keyed HMAC fixed OTP lookups but broke
every query that joined those tables back to the account, because
phone_verification*.phone_number no longer holds the same value as
driver.phone / passengers.phone. Six joins were affected, and four of them
feed the `verified` flag that the rider and driver apps check at sign-in — so
this was already failing under the current CBC mode, not only after a switch
to GCM.
Accounts now carry phone_key, computed exactly as otpPhoneKey() does, and the
joins match on it. It is written at registration for both apps and populated
for existing rows by the backfill.
The backfill also covers the columns added for the remaining lookups:
users.email_bidx/phone_bidx and driver.national_bidx, which were migrated but
never populated, and honours a per-field prefix so phone_key reproduces
otpPhoneKey's exact output.
Insert column/value counts verified with a paren-aware parser after editing.

Completes the set of queries that matched a freshly encrypted value against a
stored one, which only works while encryption is deterministic. Each keeps its
original comparison and adds an index comparison in the same WHERE, so nothing
changes today.
- passenger sign-in by email, service-staff sign-in, Firebase token lookup
- driver lookup by phone and by national number
- admin ride lookup and ride monitor (both tables)
- nabeh: driver status, user resolution, ride history, complaint submission
transit_org_admins lives in the transit database and has no index column, so
login there falls back to decrypting the small set of active admins and
comparing normalised numbers.
Schema: adds users.email_bidx/phone_bidx and driver.national_bidx with their
indexes.
Verified that every :*_bidx placeholder introduced is actually bound — an
unbound one is a fatal error at request time, not a silent miss.
