## Why
`SqliteConfig` stores its home as an `AbsolutePathBuf`, but its test constructor
previously accepted a `PathBuf` and checked the absolute-path invariant at
runtime.
## What changed
- Make `SqliteConfig::new_for_testing` accept an `AbsolutePathBuf` directly,
removing its fallible conversion and `expect`.
- Update SQLite test setup to convert temporary directory paths with
`PathExt::abs` at each call site.

## What changed
- Add `SqliteConfig` as the shared entry point for read-write and read-only SQLite pools.
- Apply consistent WAL, synchronization, auto-vacuum, busy-timeout, logging, and pool-size settings to writable Codex databases.
- Route state runtime, audit, CLI, and test database connections through the shared configuration.
## Testing
- Run migration tests against temporary on-disk databases opened through `SqliteConfig`, including the concurrent-writer repair case.

## Why
Remote-control runtime enablement and persisted enrollment preference
were represented by separate flags. That made startup rehydration, RPC
persistence, and new-enrollment seeding race with one another, and it
did not cleanly distinguish runtime-only CLI or daemon starts from
durable app-server RPC changes.
## What Changed
- Replace the parallel enablement, seed, and rehydration flags with one
transport-owned `RemoteControlDesiredState`.
- Add nullable enrollment-scoped persistence and preserve existing
preferences during enrollment upserts.
- Rehydrate plain startup only after auth and client scope resolve,
without overwriting a concurrent RPC transition.
- Make ordinary `remoteControl/enable` and `remoteControl/disable`
durable while retaining `ephemeral: true` for runtime-only callers.
- Have the daemon explicitly request ephemeral enablement and regenerate
the app-server schemas.
## Verification
- Covered migration and `NULL`/`0`/`1` persistence round trips.
- Covered plain-start rehydration and runtime-only versus durable
enrollment seeding.
- Covered durable enable, durable disable, and ephemeral enable through
app-server RPC.
- Covered the daemon's exact `{ "ephemeral": true }` request payload.
