feat(jobs): order @OnApplicationStart with priority element (PF-118, release 1.13.27)

Adds `int priority() default 0` to @OnApplicationStart; JobsPlugin sorts
discovered jobs ascending (0 = highest, stable ties) before running them,
mirroring the @Before/@After interceptor convention. Synchronous jobs gain a
hard ordering guarantee; async jobs are submitted in priority order but still
run concurrently. Backward-compatible: unset priority defaults to 0 and a
stable sort preserves today's classloader order. Includes manual + cheatsheet
docs and a unit test for the ordering key. Bumps baseversion to 1.13.27.
