steve 8fb1c100fd P2-04.5: kill host.default_paths in favour of manual schedules
Two independent path lists for "what does this host back up?" was
a real divergence footgun — operator types one set at Add-host time
and a different set into a schedule, both end up in the same repo,
the snapshot history looks fine until restore. Resolution: drop
host.default_paths entirely; add a `manual` flag on schedules.
A manual schedule has paths/excludes/tags/retention like any other
but no cron — it fires only via per-schedule Run-now. Single source
of truth for what gets backed up.

Schema (migration 0007):
* schedules.manual INTEGER NOT NULL DEFAULT 0.
* For every host with non-empty default_paths, seed a manual
  schedule with those paths and bump host_schedule_version.
* ALTER TABLE hosts DROP COLUMN default_paths.
* ALTER TABLE enrollment_tokens RENAME COLUMN default_paths
  TO initial_paths.

Original draft of this migration rebuilt hosts via the
create-new + drop-old + rename-new pattern. With foreign_keys=ON
(set in the connection DSN), DROP TABLE on the parent fired
ON DELETE CASCADE on every child of hosts(id) — schedules /
jobs / snapshots / host_credentials all wiped on the smoke env
when I tried it. SQLite 3.35+ supports column-level ALTERs
directly, so we skip the rebuild dance and avoid the cascade
trap. Six lines of SQL instead of sixty, no FK risk.

Run-now rewiring:
* New `dispatchScheduleNow(hostID, scheduleID, conn?)` helper
  unifies the agent-driven path (cron fire → schedule.fire →
  OnScheduleFire callback) and the UI-driven path (operator
  clicks Run-now on a schedule row). Conn arg is optional; nil
  falls back to Hub.Send.
* New POST /hosts/{id}/schedules/{sid}/run endpoint — per-row
  Run-now button on the schedules list.
* Dashboard's per-host Run-now (handleUIRunBackup) now picks the
  host's only enabled manual schedule, falls back to the only
  enabled schedule, else returns "pick one in Schedules tab".
  Keeps one-click for the common case.

Agent:
* Scheduler skips manual schedules in cron build (silent — they're
  a normal data shape, not an error).
* Wire Schedule struct gains Manual flag.
* Schedule.fire flow unchanged — the agent only ever fires
  non-manual schedules anyway.

UI:
* Add-host form retitled "Initial schedule · manual" so the
  operator knows the paths become an editable schedule under
  the Schedules tab. Result page calls out the manual schedule
  + points at Host > Schedules.
* Schedule edit form: "Manual schedule" checkbox at the top of
  the When section; toggling it hides/shows the cron field via
  inline JS. Server-side validator skips the cron requirement
  when manual=true.
* Schedule list shows a "manual" tag under the status pill and
  renders the When column as "— run-now only —" for manual rows.
  Each row gets a Run-now button when the schedule is enabled
  and the host is online.

Tests + go test ./... green.

steve 608962441b P2-02 (agent side) + P2-03: agent scheduler + schedule.fire dispatch
Closes the schedule reconciliation loop end-to-end.

* New `internal/agent/scheduler` package wraps robfig/cron/v3 with
  the lifecycle the agent needs:
  - Apply(ScheduleSetPayload, Sender) stops the prior cron (waiting
    for in-flight entries to return), rebuilds from scratch, starts,
    and emits schedule.ack with the version we just applied.
  - Disabled entries skipped silently; bad cron exprs (which
    shouldn't reach us — the server validates — but defensive)
    log a warn and skip.
  - On each cron tick the entry sends a new schedule.fire envelope
    to the server with {schedule_id, scheduled_at}. The scheduler
    itself never builds CommandRunPayloads — server is the source
    of truth for jobs.
  - tx is swapped on every Apply, so reconnect is handled
    naturally: cron entries that fire against a dropped tx log
    "no active connection" and skip the tick.
  - Stop() is idempotent and waits for the cron's in-flight
    workers via cron.Stop().Done().

* New wire message api.MsgScheduleFire + api.ScheduleFirePayload
  for the agent → server "I just fired locally" RPC.

* Server-side dispatch (schedule_push.go: dispatchScheduledJob):
  looks up the schedule by id, validates ownership + that it's
  enabled, builds args from kind (paths for backup; other kinds
  are still arg-less in Phase 2 and grow as those job kinds land
  in P2-05..08), persists a jobs row with actor_kind=schedule +
  scheduled_id, and writes command.run back on the same conn so
  the agent runs through its existing dispatch path.

* store.CreateJob now writes scheduled_id. This column was in the
  schema since 0001 but never populated — the original P1 path
  only had operator-driven jobs, so actor_kind was always 'user'
  and scheduled_id was always nil.

* cmd/agent/main.go integration: dispatcher gains a
  *scheduler.Scheduler; the MsgScheduleSet case now hands the
  payload to scheduler.Apply (in a goroutine so the WS read loop
  keeps draining other messages).

* WS dispatcher gains OnScheduleFire alongside OnScheduleAck.

* Tests:
  - scheduler unit tests (4): ack-on-apply, cron tick fires
    schedule.fire envelope, disabled entries don't fire, replace-
    prior-state stops the old cron.
  - Server-side end-to-end: schedule.fire → command.run with the
    right job_id / kind / args, plus jobs row with actor_kind=
    "schedule" and scheduled_id linking back to the schedule.

Persistence of next-fire times across agent restarts is
deliberately deferred. A missed fire window during downtime
simply fires once on reconnect — that's the desirable behaviour
(the operator wants the missed backup to run, not be silently
skipped because we lost track of when it was due).
