Is your feature request related to a problem? Please describe.

Currently, only the most recent tasks are shown in the customer box.
For any less frequently used tasks, I first have to select Customer -> Project -> Task

This is slow when:

• the task name is known but the customer and project need to be selected first
• a task is used rarely (it never appears in the recent-tasks list),

Describe the solution you'd like

A search by task name (and ideally customer/project name) directly in the customer box.
Typing a term shows a list of matching Customer > Project > Task combinations; selecting one fills all three dropdowns at
once.

Suggested behavior:

• Search terms are whitespace-separated and may match any of customer, project, or task name,
  in any order (e.g. acme deploy finds task "Deployment" of project "Website" of customer "ACME").
• Matching is done server-side (GET /api/v1/tasks?search=…) so the frontend never has to
  build the full list of Customer>Project>Task combinations.
• Requests are debounced, require a minimum term length, and the result count is capped
  (e.g. 20 via page[size]) to keep load negligible.
• Recent tasks and customer-name matching in the same box keep working as before;
  global matches are appended below them.

Describe alternatives you've considered

• Building all combinations client-side -> memory/load on the backend would be high
• A separate, dedicated search box -> possible, but the customer box already accepts task
  options (recent tasks), so reusing it needs no new UI surface.
• A global command palette (e.g. Ctrl+K) -> nice-to-have on top, not a replacement.

Additional context

This should probably be a toggleable beta feature first. Some other ideas:

• Fuzzy matching / typo tolerance
• Ordering by relevance in search results with same names based on personal usage
• Hint at results being paginated/capped
• Highlight matched substring
• Allow hiding archived tasks / make it a toggle hiding them by default
