Two engine bugs caught by Task 19's integration tests:
1. Partial reconcile (bank_amount < invoice_residual) was creating an
unbalanced bank move. Counterpart balance now clamped to
min(remaining_bank_amount, abs(invoice_residual)) so the move stays
balanced; Odoo's reconcile() handles the resulting partial. The
counterpart's amount_currency is scaled proportionally so multi-
currency lines stay consistent.
2. Unreconcile only removed account.partial.reconcile rows but didn't
restore the suspense line on the bank move, leaving is_reconciled=True
after unreconcile. Now delegates to V19's standard
account.bank.statement.line.action_undo_reconciliation for any
affected bank line, which both deletes partials and restores the
suspense state in one shot.

Adds fusion.reconcile.engine — the AbstractModel orchestrator for all
bank-line reconciliations. Six public methods (reconcile_one,
reconcile_batch, suggest_matches, accept_suggestion, write_off,
unreconcile) form the only sanctioned write path to
account.partial.reconcile from the rest of the module (controllers, AI
tools, wizards).
Implementation follows V19's bank_rec_widget pattern: rewrite the bank
move's suspense line into one counterpart per matched invoice (or a
write-off line) on the appropriate receivable / payable / write-off
account, then call account.move.line.reconcile() on each pair. Records
a precedent row per reconcile for downstream pattern learning.
16 new unit tests cover all six methods across happy paths, the
precedent side effect, suggestion lifecycle, batch auto-strategy, and
write-off line clearance. 67 total tests, 0 failed.
