feat(server): source-tagged logs and parameterized scheduled jobs

[Sootopolis]

What

Two improvements surfaced by running CcasServer in the foreground.

Log source attribution. Every app/job logged to one undifferentiated console stream. Reuses ZIO log annotations (the formatter already rendered them; nothing set them): ProgressDisplay.sourced sets a reserved src key that format renders as a bracketed prefix — lines now read [INFO 14:03:22] [Membership/london-cc] msg.

• Jobs tagged [Kind/slug] at JobRunner.submit (single choke point; slug best-effort, #id fallback, kind-only for global jobs).
• Global logs stay global: rate-limit warnings tag [rate-limit], scheduler poll logs [scheduler] — attributable even when running on a job's fiber.
• No-annotation path is byte-identical, so CLI standalone apps are untouched.

Parameterized scheduled jobs. job_schedule.params was stored but the scheduler ignored it, forcing hardcoded defaults (e.g. a full ClubData refresh every tick). New ScheduleParams decodes per-kind option DTOs and threads them into the app calls.

• Absent/blank params decode to the previous defaults exactly — existing schedules unchanged.
• Decode is eager (before submit), so a malformed row is isolated by the existing poll guard without advancing last_run_at.
• Recruitment caps moved to a shared JobCaps so the HTTP and scheduled paths bound identically.
• Author via the existing flag: schedule add clubData --interval-hours 24 --params '{"minAgeHours":24}'. minAgeHours is opt-in (deriving from the interval would skip every club forever on a steady cadence).

Fixes

None (no linked issue).

Testing

• sbt test — 1013 pass, 0 fail (pre-push hook + local).
• New TestScheduleParams (decode defaults / populated / malformed / stats both-or-neither).
• TestProgressBar +1 (src renders as prefix, other annotations stay trailing).
• TestJobScheduler +2 (params reach submit; malformed row doesn't block other schedules).
• Verified live in test output: [INFO ..] [MatchRef] hello from job.
