feat: make repo selector searchable on create issue form

Replace the plain <select> with an HTML5 <input> + <datalist> pair so
users can type to filter repositories. Add debounced input handler for
label loading, change event for direct datalist selection, and client-side
validation that the entered value is a known repository.

Closes leeworks-agents/gitea-mobile#87
