File Cabinet MVP: case detail with inline Ledger CRUD

- Extend Transaction with ledger fields (item_no, employee_number, t_code, t_type_l, quantity, rate, billed)
- Startup SQLite migration to add missing columns on transactions
- Ledger create/update/delete endpoints with validations and auto-compute Amount = Quantity × Rate
- Uniqueness: ensure (transaction_date, item_no) per case by auto-incrementing
- Compute case totals (billed/unbilled/overall) and display in case view
- Update case.html for master-detail ledger UI; add client-side auto-compute JS
- Enhance import_ledger_data to populate extended fields
- Close/Reopen actions retained; case detail sorting by date/item
- Auth: switch to pbkdf2_sha256 default (bcrypt fallback) and seed admin robustness

Tested in Docker: health OK, login OK, import ROLODEX/FILES OK, ledger create persisted and totals displayed.
