Reliability fixes and day-to-day polish

Gear marked lost, decommissioned, or archived can be set back to Active again when you edit and save the record. The UI was already sending the right data; the update API now clears the inactive reason instead of keeping the old value.

Categories and locations are safer to manage when legacy data has duplicate names. Deleting one row no longer removes every row with the same name, and trying to add a duplicate name shows a single clear message instead of a generic server error.

The dashboard’s Recently closed repairs section now lists only completed work orders. Open tickets no longer appear there with a misleading Closed badge.

If the gear scanner camera fails to start, you see one clear error instead of a stack of repeated toasts. The scanner still retries a few times in the background; use Reset to try again manually.

Gear, repair tickets, categories, locations, and users now sort alphabetically in lists and dropdowns. Access logs and reservations still sort by date and time.

On Reservations in list view, filter by All, Upcoming, or Past. Upcoming is the default and includes active and scheduled events; Past shows completed reservations, newest first. Calendar view is unchanged.

On the gear form, click a tag to rename it instead of removing and re-adding it. View mode shows tags as read-only badges that match the inventory list.

Inventory reports and CSV exports now separate checkout status, inventory status, and lifecycle status. They also include parent gear, verification checklist flags, and whether an item can contain other gear.

Gear access and user exports are flattened for spreadsheets: Gear ID and gear names resolve correctly, verification and contained-gear details appear as plain text instead of [object Object], and user rows show Name, Email, Role, and related fields.
