Fix dashbord.php parse error; require super_admin on pricing and crypto tools

Hotfix: a comment added to the dashboard SQL contained double quotes inside
the double-quoted PHP string, terminating it and making dashbord.php fail to
parse. Production was returning a parse error for every dashboard request.

Authorisation gaps closed — connect.php only proves a token is valid, it does
not check what the caller is allowed to do:

- Admin/ggg.php decrypts any database field and was authorised solely by an
  admin phone number sent in the request body. Anyone who knew a listed
  number could decrypt platform data without signing in. It now runs behind
  connect.php, requires super_admin, keeps the phone list as a second factor,
  and records every use.
- ride/kazan/update.php, kazan/add.php and ride/promo/{add,update,delete}.php
  changed live pricing and discount codes with no role check at all, so any
  valid token — including a driver's or passenger's — could rewrite the fare
  table. All now require super_admin.

Staff/pending.php: adminUser has no `status` column in this deployment, so
the query failed with an opaque "unavailable". It now checks for the column
and reports the actual reason.

Console: Kazan tariff editor for super admins — sends only changed fields,
shows an old → new confirmation before saving, and stays read-only with an
explanatory notice for plain admins.
