feat: make per-job timeout 0 mean "no timeout" instead of inherit

Browse Source 
A per-job timeout now has three distinct states: unset inherits the global
default, an explicit 0 means no timeout and does not inherit, and a positive
value is the per-job limit. Job.TimeoutSeconds became *int so unset and 0 stay
distinguishable in jobs.json.

Also fixes the global default, which could not persist a 0. loadOrCreateConfig
normalized DefaultTimeoutSeconds <= 0 back to 30 on every read of an existing
gosentry.json, so "no timeout" only held until the next restart. The field is
now written unconditionally (no omitempty) and read back as-is.

Existing jobs and configs are unaffected: a job with no timeout_seconds still
inherits, and a saved global default of 30 stays 30.

### Per-job command timeout
`domain.Job` carries a `TimeoutSeconds` field (`json:"timeout_seconds,omitempty"`),
following the same inherit pattern as the overlap policy. `0` means inherit the
global `Config.DefaultTimeoutSeconds` (default **0**, i.e. no timeout); a
positive value overrides it for that job alone. `app.Service.effectiveTimeout`
`domain.Job` carries a `TimeoutSeconds *int` field
(`json:"timeout_seconds,omitempty"`), following the same inherit pattern as the
overlap policy. It is a **pointer** because the setting has three states that
must stay distinguishable on disk:
| `Job.TimeoutSeconds` | jobs.json | Meaning |
| --- | --- | --- |
| `nil` | field absent | inherit `Config.DefaultTimeoutSeconds` |
| `0` | `"timeout_seconds": 0` | no timeout, does **not** inherit |
| `> 0` | `"timeout_seconds": 45` | per-job limit in seconds |
The global `Config.DefaultTimeoutSeconds` (default **0**, i.e. no timeout) is
written unconditionally — no `omitempty` — for the same reason: `0` there is a
deliberate choice, not a missing value, and `storage.loadOrCreateConfig` must not
normalize it away. `app.Service.effectiveTimeout`
resolves the effective duration under `mu` and `startRunLocked` snapshots it into
`runEnv.timeout`. `runner.RunJob(ctx, job, trigger, logsDir, timeout)` takes the
resolved duration as an argument, so the runner stays ignorant of the global
