Check-in now also returns "auftraege": the full present/absent state
of every catalog-eligible Merkmal (im_auftragskatalog = true) for the
device's backend, derived statelessly from device_merkmale rather than
just the workspace-resolved blueprints list, which stays untouched.
This is what lets a deselected Auftrag actually be reverted once the
corresponding Ansible role grows an absent branch (ADR-0010) - the
agent doesn't have that branch yet, so this is additive and inert
until it does.
Adds POST /api/v1/agent/report so the agent can write execution
results (applied/apply_failed/removed/remove_failed) back into
device_merkmal_events; selected/deselected is intentionally rejected
here since those are meant to come from wherever Auftrag selection
ends up being triggered, not from the agent itself.
Migration 0007 adds the backing tables (kategorien, device_merkmale,
device_merkmal_events) and the two new merkmale columns.
Verified against anode: checkin toggles present/absent correctly
after inserting a device_merkmale row, report endpoint accepts valid
entries and rejects unknown merkmale / non-agent event types / bad
secrets, and the written event round-trips through device_merkmal_events
correctly as jsonb.
