feat: ACM HR

[LukeSultzer]

Summary

This issue tracks the implementation of three features under the ACM HR tab: a searchable officer selector, the ability to delete officers from Firebase (with a confirmation guard), and a strike system (max 3) visible only to Exec users in the Officer View.

Officer search

• Add a search input under the ACM HR tab to locate and select an officer
• Search should filter officers in real time by name
• Selected officer context drives deletion and strike actions below

Officer deletion

• Provide a Delete Officer action for the selected officer
• Show a confirmation prompt — have to type officer full name before any write occurs
• On confirmation, fully remove the officer from Firebase
• On cancellation, take no action and return to the HR view

Strike management

• Allow Exec users to assign strikes to officers (max 3 per officer) and add a description, date given, title.
• Store strike count on the officer's Firebase record
• Have a striked officers view only shown on the hr tab
• Strike count is visible to Exec users only — all other roles must not see this field!!!!!!!
