Show spool availability indicator per job on jobs list

- filamentdb.spool_counts(): builds (material, color_name) → roll count
  from cached stock report; counts rolls_in_stock + rolls_in_use (non-graveyard)
- Jobs list: coloured dot before material — green (2+), yellow (1), red (0)
- FILAMENTDB_URL added to .env
