Add spreadsheet-style home page, migrate full 2026 ledger

- New /lignes route (set as site front page): full line-by-line table of
  every ligne comptable, Vue app with filters (compte/client/type/année)
  and month/year grouping, columns matching the original spreadsheet
  (one per compte). Rows with répartition ≠ montant HT are visibly
  flagged (red row + écart column), not hidden or auto-corrected.
- /dashboard now only holds the aggregate solde-par-compte/par-client view
- Migrated all 199 real 2026 transaction lines + 9 opening balances (from
  REPORT CLOTURE 2025) via a drush import script, preserving raw source
  data (known répartition mismatches included) -- validated with a new
  state-flag bypass of the presave check, used only for historical import
- Added "Autre" as an allowed field_type_ligne value for edge-case rows
- Client taxonomy grew from 15 seeded terms to the full unified list
