Complete USB self-hosted mode (app tables, no external cmmc_usb)

"Create the tables here" for USB now actually works. Add selfhosted.py backing
every USB endpoint with the app-owned usbdevices/usbcheckouts tables and
returning the same response shape as the external cmmc_usb path. Each route in
routes.py delegates to it when usb_directory_mode=selfhosted (the default).

- Device status derives from ischeckedout + isactive (retired); check-in/out
  history is synthesized from usbcheckouts rows (check-out + check-in events);
  holder names resolve from the self-hosted employee directory.
- External cmmc_usb mode unchanged, for sites already running that solution.

Verified E2E: create -> list -> checkout -> checkin -> history all correct
against the app tables.

"""USB plugin API endpoints.
Check-in/out state lives in a separate MySQL database (cmmc_usb), reached with
raw parameterized pymysql via cmmc_usb_connection(), mirroring the read-only
employee-directory helper pattern. The SQLAlchemy USBDevice/USBCheckout/
USBDeviceType models in ../models are NOT used by these routes anymore; they
are left in place for any legacy importers.
Two modes, chosen by the usb_directory_mode setting:
- 'selfhosted' (default): the app-owned tables (usbdevices/usbcheckouts/
usbdevicetypes) via SQLAlchemy - see selfhosted.py. Each route below
delegates when _usb_selfhosted() is true.
- 'external': a separate MySQL database (cmmc_usb) reached with raw
parameterized pymysql via cmmc_usb_connection(), for a site that already
runs the cmmc_usb solution. That is the raw-SQL code in this file.
Both modes return the same response shape so the frontend is identical.
