New bugs

• New "file does not exist" issue
  1. Create a new file
  2. The URL changes to something like https://clt.manticoresearch.com/?test_path=core%2Ftest.rec
  3. Refresh the page
  4. You'll see the error: Error: File "core/test.rec" does not exist.
  

• When I hover over the button, it becomes invisible:
  

• The branch is not pushed to GitHub
  
  The link goes to https://github.com/manticoresoftware/manticoresearch/tree/sergey-clt-20250821, but the branch is missing.

I'll add more items here as I find other minor issues.

• We should add protection from running CLT tests from the OLD repository when we have a missing .clt directory because the directory is bound by default as root and gives us huge problems with branch resetting.

All done in #103
