Locate jobs/ directory from deployment package in daemon

**Epic:** #1080

In `internal/daemon/consensus/upgrade_monitor.go`, derive the `jobs/` path from the existing `upgrade_dir` config field (already in `daemon.yaml`). Reuse the same derivation for install handlers in `bll/`.

## Acceptance Criteria
- [ ] `jobs/` path correctly derived for upgrade and install contexts
- [ ] Missing `jobs/` dir treated as no-op (consistent with HIP-1494 optional semantics)
- [ ] Path logic unit tested

Start in internal/daemon/consensus/upgrade_monitor.go and inspect the existing upgrade_dir configuration in daemon.yaml. Trace the install handlers under bll/ to apply the same path derivation, then locate the daemon unit-test conventions and add coverage for upgrade and install contexts. Done means the jobs/ path is correct and a missing directory is treated as a no-op.
