AP-039 Cross-Entity Global Search

[Basichy]

Adds a global search box in the admin navbar that searches users, guards, and shifts at once.

• Aggregates the existing users and shifts list data (client-side for now)
• Matches on name, email, or ID
• Groups results by Users / Guards / Shifts
• Debounced, 2-character minimum
• Click a result to jump to its detail page (shifts link to the filtered Shifts list, no detail page yet)
