feat: add tx edit and tx delete (v0.3.0)HEADv0.3.0master

Implements ISSUES.md #1, the missing other half of an import tool:
correcting and removing mis-imported transactions without the web UI.

- tx edit <id>: PATCH a single-split journal; only the fields passed are
  sent (--amount/--date/--desc/--from/--to/--category/--tags/--type). Errors
  if no field is given. Accounts resolve to ids; category/tags pass raw.
- tx delete <id>: requires --yes (no interactive prompt, agent-first);
  prints {"deleted": "<id>"} on success.

Also fix gen_completion.py: running it as a script put scripts/ on
sys.path[0] and imported the installed (stale) firefly_cli, so the
generated completion drifted (missing account balance/get, tx get/search).
Prepend the repo root so the documented regen command uses this tree. The
regenerated completion now reflects the full command surface.

MINOR bump per the contract-keyed scheme: new commands, no breaking change.
