Quick-action a bot (recharge / toggle servicing)

[CarsonL15]

As an admin, I want one click actions to recharge a bot or toggle its servicing status, so that I can resolve common issues without opening an edit form.

Acceptance criteria:

• A "Recharge" button calls PUT /api/bots/{id}/recharge and sets battery to 100
• The Recharge button is disabled when battery is already 100
• A "Mark Active/Idle" button calls PUT /api/bots/{id}/servicing-status
• The button label and status pill update without a page reload
