feat(inventory): add Asset Maintenance tracking with GL posting

Closes the remaining gap in the fixed-asset lifecycle (acquisition,
depreciation, disposal/sale already existed) by adding a maintenance
log per asset with cost, vendor, and next-due tracking. Each category
now carries its own maintenance expense account, mirroring how
depreciation and disposal are already mapped, and maintenance cost
posts Dr expense / Cr cash-bank-payable through the same operational
posting pipeline.
