refactor(v2): cassette CRUD + transport — position-keyed (#29 v1.1)

Browse source 
CRUD layer flips:
  - get_cassette_config(machine_id, position) — was (..., denomination)
  - list_cassette_configs_for_machine returns ORDER BY position alone
    (no secondary denomination ordering — position is the unique key)
  - update_cassette_config(machine_id, position, data, updated_by) —
    operator edits denomination + count for a fixed slot
  - apply_bootstrap_state upserts ON CONFLICT(machine_id, position)
    iterating payload.positions; populates new state_denomination
    column from row.denomination alongside state_count

cassette_transport.py needs almost no functional change — the wire
shape is implicit via PublishCassettesPayload.to_wire_dict (now emits
{"positions": {...}}) and decrypt_and_parse_state_event accepts what
the model parses. Just the module docstring + the publish log line
get updated to reference positions rather than denominations.

Tests still red until commit f rewrites them.
