Backup names were built inline from Date#getMonth, which is zero-indexed, so a backup taken on 12 September 2026 was written as db_2026-8-12_20-35-56.sqlite. No field was zero-padded either, giving names like db_2026-8-12_20-36-2.sqlite. Extract formatBackupTimestamp into server/lib and use it from both places that built the string: the backupDb helper in migrationsSqlite.ts and the inline copy in the 1.0.0-beta9 setup script. Padding every field also makes the names sort lexicographically in the order the backups were taken. Adds tests covering both reported names, single-digit padding and sort order. Reverting the helper to the old formula fails them with the exact name from the report.

/**
|
|
* Builds the timestamp segment of a database backup file name.
|
|
*
|
|
* `Date#getMonth` is zero-indexed, so building this inline produced names like
|
|
* `db_2026-8-12_...` for a backup taken on 12 September 2026. Every field is
|
|
* also zero-padded, which keeps the names unambiguous and makes them sort
|
|
* lexicographically in the order they were taken.
|
|
*
|
|
* @param date The moment the backup is being taken. Defaults to now.
|
|
* @returns A timestamp of the form `YYYY-MM-DD_HH-MM-SS`.
