debugger: Fix breakpoint list not showing breakpoints in single files (#63348)
# Objective
- Currently there is a bug where breakpoints in single files (not in
folder/worktree) are not shown in the debug panel breakpoint list. They
visually make the breakpoint list empty
- This is because we try to create a `RelPath` from `breakpoint.path`,
which is an absolute path
## Solution
- Create the fallback directory string in a valid way
- Because breakpoint directories can now be absolute, the first part of
the path isn't always the worktree root, so we can't blindly skip this
in the UI code anymore
- Instead, only prepend the worktree root if there multiple worktrees,
matching behavior of other UI elements. This simplifies the code overall
## Testing
- Manually tested
