Fix account dropdowns: vendor auto-select + sub-type filtering

Inventory vendor auto-select: match the dropdown off the Manufacturer
field (almost always populated and equal to the vendor for the shop's
distributors) instead of the AI's price-conditional vendorName, which was
only returned when a price was scraped. Centralizes the logic in a shared
inventory-vendor-match.js used by catalog lookup, AI lookup, label scan,
and manual entry; skips brands sold by multiple distributors (PPG, KP
Pigments) so those stay manual.

Account dropdowns filtered by sub-type now filter by parent AccountType,
so accounts a company classifies under a non-standard sub-type still
appear: Inventory account (Asset), AP account (Liability), pay-from/bank
and Bank Reconciliation pickers (Asset + Liability).

Deposit account is now a user-selectable dropdown on the Job and Quote
deposit modals (Asset + Liability accounts) instead of a silent auto-pick
of the first Checking/Cash account; falls back to the old behavior when
left blank, and validates the chosen account belongs to the company.
