[Feature-Request] Search tasks by "add task"-texbox

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

Problem: Big list and want to see all tasks that contain some words and handle all these similar ones (e.g. put some of them to another list and other things; reorganize them, change them).

Describe the solution you'd like

Proposed solution:
Add a small button left to tag-filter and ordering buttons. E.g. magnifer glass with "live" symbol (or lighning/thunderbolt). Then when one writes into the textbox, the list is reduced to all items which contain the words (on each key type further reduction).

Describe alternatives you've considered

Current solution: In https://github.com/nextcloud/tasks/pull/2427 usage for the global search was introduced. This allows to search and see the tasks, on clicking them, the page reloads the page and after a short time one sees a list with all the tasks and the clicked one, which is highlighted.

Problem with this solution:

• separate search page and small loading overhead (and back and forth)
• only gives the option to edit one single item and not multiple in one sight (in accordance)

Additional context

No response

Review the global-search implementation introduced in pull request #2427, then inspect the existing tag-filter and ordering controls mentioned in the request. The work is done when a local textbox filters the current task list as text is entered, while leaving matching tasks visible together for further handling.
