fix(proxy): unset DB environment variables removed from the row on every worker by row revision (#46709)
* fix(proxy): unset DB environment variables removed from the row on every worker by row revision

* fix(proxy): order the environment variables revision migration after main's and set its lock timeout

* fix(proxy): snapshot the environment at the first DB sync even when no environment_variables row exists yet

* fix(proxy): close gaps in DB environment variable reconciliation

Grant the revision sequence to every role so a writer role with only
table grants can still save environment_variables. Unset SSO keys that
only the environment_variables row stored on the next SSO sync, while
keeping keys the SSO settings table holds. Skip a revision-less row once
a revision has been applied, so a stale cached row cannot bring a
removed key back. Keep plaintext and undecryptable values when rotating
the master key instead of dropping them from the row.

* fix(proxy): keep env var revisions monotonic across DB copies and restores

Stamp at least the old revision plus one on update so a copied row keeps
rising, re-read a stale cached row from the writer and apply it when the
database itself went back, unset dropped SSO keys when sso_settings are not
loaded from the DB, and keep env values master key rotation cannot decrypt
exactly as stored

* fix(proxy): skip an env var row read before an overlapping sync that already applied a newer one

* test(proxy): cover a read replica back on an older row and an SSO client removed from DB environment_variables

* fix(proxy): keep config reads up when the writer is down, find the revision sequence by table schema, read the writer before rewriting env vars, and add the trigger under db push

* test(proxy): model the writer database in the retry policy config update fake

* fix(proxy): recheck the environment_variables row revision right before applying it

A sync that started later could read a stale environment_variables row
before an earlier sync applied a newer one, then pass the read-order check
and apply the stale row, bringing back keys the newer row removed. The
behind-the-applied-revision check now runs at apply time, re-reading the
writer when the row is behind, and a writer row read while another sync
applied a newer revision is dropped.

The config sync tests now inject a fake database client and use the real
get_config_param and its cache instead of replacing get_config_param.

* test(proxy): keep encryption real in the SSO replica-lag test

* test(proxy): inject a fake Prisma client in the env var replica-lag test

* fix(proxy): keep the applied environment variables when the writer database is out of connections

* test(proxy): cover a writer database out of connections in the env var integration tests
