2306562c01 auth: add defensive has() guard for role_attributes value column
Add a has() check before accessing the value column in role_attributes
to tolerate ghost rows with missing regular columns. In practice this
is unlikely to be a problem since attributes are not typically revoked,
but the guard is added for consistency and defensive programming.

3f35b3bc55 auth: remove unused permissions field from cache role_record
The permissions field in role_record was populated by fetch_role() but
never read. Authorization uses cached_permissions instead, which is
loaded via the permission_loader callback. Remove the dead field and
its fetch code.

The removed code also did not check for missing columns before accessing
the permissions set, which could crash on ghost rows left by the removed
auth v2 migration. The migration used INSERT (creating row markers),
and when permissions were later revoked, the row marker survived while
the permissions column became null.

3c1e1f867d raft: auth: add semaphore to auth_cache::load_all
Auth cache loading at startup is racing between
auth service and raft code and it doesn't support
concurrency causing it to crash.

We can't easily remove any of the places as during
raft recovery snapshot is not loaded and it relies
on loading cache via auth service. Therefore we add
semaphore.

4df6b51ac2 auth: fix cache::prune_all roles iteration
During b9199e8b24
reivew it was suggested to use standard for loop
but when erasing element it causes increment on
invalid iterator, as role could have been erased
before.

This change brings back original code.

bd7c87731b auth: add unified cache implementation
It combines data from all underlying auth tables.
Supports gentle full load and per role reloads.
Loading is done on shard 0 and then deep copies data
to all shards.
