Commit Message

fix(stack): give each Mailpit instance its own database (#6901)

## Summary

The stack starts Mailpit without a database path, so Mailpit uses a
temporary SQLite file named from the current time under the system temp
directory and deletes it on every stop. Two native stacks waking mail
together could end up on the same file, and one Mailpit exited with
`database is locked (5) (SQLITE_BUSY)`; Auth could then not wake and
`/signup` returned 502 in the native parallel-stacks e2e. Because Mail
is a lazy member with an idle stop, captured emails also disappeared
after a minute without traffic.

- Process-recipe services can opt in to an owned instance directory
(`<stack data root>/<instance id>`), claimed and removed through the
same ownership marker logic the Database service uses, now shared in
`services/InstanceRoot.ts`. Natively the recipe receives the host path;
in containers the directory is mounted at `/instance`.
- Mail opts in and sets `MP_DATABASE` to `mailpit.db` in that directory,
so each instance has its own database, emails survive idle sleep and
stop/start, and destroying the instance or stack removes them.
