DottaandPaperclip e704e1c9ae fix: keep AI subscription locks safe through transaction pooling (#13347)
## Thinking Path

> - Paperclip manages AI agents and their credentials.
> - AI Connections must preserve account ownership from login through
execution.
> - A subscription environment check can pass and leave a session
advisory lock on a pooled database backend.
> - The next execution then reports that the subscription is busy.
> - Onboarding can also lose its completion callback when the connection
list refreshes before the login poll.
> - This change keeps each credential lease in one transaction and keeps
the login controller mounted until completion.

## Linked Issues or Issue Description

Refs: #13247, #13248, #13344.

**What happened?**

A real hosted subscription login saved successfully and passed its
environment check. The first task then failed with an AI connection busy
error. A connection-list update could also leave onboarding on
Connecting.

**Expected behavior**

A completed environment check releases its credential lease. A saved
login completes onboarding without another sign-in.

**Steps to reproduce**

1. Run Paperclip with a transaction-pooling PostgreSQL proxy.
2. Connect a Claude subscription through onboarding and reuse it for an
agent.
3. Start a task after its environment check succeeds.
4. For the UI race, refresh the managed connection list before the login
completion poll.

## What Changed

- Hold the grant lock inside one transaction. Roll back on cleanup or
failed acquisition.
- Disable the lease transaction's idle timeout so long provider
executions retain the lock.
- Keep the onboarding login controller mounted while its authorization
URL is active; restore saved-account retry if later agent creation
fails.
- Add lock-lifetime and Claude/Codex completion-order regressions.
- Document the pooling requirement.

## Verification

- 104 focused connection and onboarding tests passed.
- Workspace typecheck, production build, Storybook build, and token
gates passed.
- All 34 latest-head checks are terminal: 32 passed and two Storybook
workflows skipped by their normal filters. CI covers all
server/workspace/serialized test shards, browser tests, typecheck,
build, runner verification, and canary packaging. The additional local
full-suite run is still in progress.
- Real browser sign-ins saved Claude and OpenAI subscriptions on both
new and existing staging stacks. On the patched new stack, both
providers completed tasks and immediate repeat executions with the same
saved accounts. Read-only database inspection confirmed live
transaction-scoped locks and no remaining locks after completion. On the
final deployed head, both shared accounts on the existing stack also
completed actual tasks. Both personal accounts passed a fresh
environment check followed immediately by execution after a deployment
restart.

## Risks

- Each active subscription reserves one database connection and holds an
otherwise idle transaction until cleanup. This is required to pin the
backend through a transaction pool.
- Old session locks from earlier versions may need operator cleanup
after active runs drain. This change does not bypass existing locks.
- No database migration, credential routing, or legacy authentication
change.

## Model Used

OpenAI GPT-6 in Codex, with code execution and browser tools. The exact
deployment model ID and context-window size are not exposed to this
task.
