feat(fusion_accounting_assets): fusion.asset.engine 7-method API

The orchestrator AbstractModel for asset depreciation lifecycle.
compute_depreciation_schedule, post_depreciation_entry, dispose_asset,
partial_sale, pause_asset, resume_asset, reverse_disposal.

All controllers, AI tools, wizards, and cron must route through these
methods; no direct ORM writes to fusion.asset.depreciation.line or
account.move from anywhere else.
