Closes #35898

Implementation Summary

This PR implements three key improvements to Gitea’s repository file browsing experience based on GitHub’s interface:

1. Repository-Wide File Search

• Added search functionality with real-time filtering
• Git grep-based search showing line numbers and matched content
• “View File” navigation for each search result
• Exceeds requirement: Full repository search vs basic tree filter

2. Add File Dropdown Menu

• Dropdown button with three options:
  • New File
  • Upload File
  • Apply Patch
• Top-right placement in repository view

3. Context Menu (Three-Dot Menu)

• Three-dot menu in repository view
• Download options (ZIP, TAR.GZ, BUNDLE)
• IDE integration options (VS Code, VSCodium, IntelliJ IDEA)

Files Modified

1. web_src/js/features/repo-tree-search.ts - Search functionality (250+ lines)
2. web_src/js/index-domready.ts - Feature integration
3. templates/repo/view_list.tmpl - UI components (search box, file actions)
