`upgradedb()` has a fast path for fresh databases: when there's no current
revision and no explicit `to_revision`, it delegates to `initdb()` which
handles pool creation. But when `to_revision` is set (e.g. `airflow db migrate
--to-version 3.1.8`), it skips `initdb()` and goes straight to
`_run_upgradedb()` — never calling `add_default_pool_if_not_exists()`.
Result: tasks stuck in "scheduled" forever because the scheduler sees zero
pool slots.
Fix: after `_run_upgradedb()` on a fresh DB with explicit revision, call
`add_default_pool_if_not_exists()` and `synchronize_log_template()` to match
what `initdb()` does.
Closes: #63551
