Type formulas for unit prices and recognize projects by name

Unit Price fields now support arithmetic formulas, and projects display by name and address across the app.

Improvements

Unit Price fields on estimates and invoices now accept arithmetic formulas — type 4.5 * 1.3 and it resolves to the price instantly, with line totals updating live.

Projects across the app (tasks, timesheets, work orders, estimates, calendar, dashboard) now display by their name, property address, or project number instead of bare project codes — making it easier to identify the right job.

Non-salvageable items are now consistently excluded from pack-out views, matching other inventory phases.
