Post-initial polish: voicemail SQL fix, README, .env in local ignore

- route_plan.py: drop `NULL AS context` from voicemail_pilot_css query.
  Informix rejected it as a syntax error; the column wasn't carrying any
  signal anyway, so the simpler SELECT works and matches the other
  reference-point queries.
- README.md: tool table now covers all 16 tools (route_device_pool_route_groups,
  route_devices_using_css, route_filters were missing).
- .gitignore: explicitly ignore .env. Already covered by ~/.gitignore_global,
  but worth being self-contained — anyone cloning without the global ignore
  shouldn't be one stray `git add` away from leaking AXL credentials.
