## Summary

Filenames containing md syntax (e.g. `__somefile__`, `*somefile*`) were
being rendered as markdown text in the file deletion confirmation
dialog.

Fixes #55651

## Changes

Wrapped file paths with `MarkdownEscaped` in the single and multi-file
deletion confirmation dialogs in `project_panel.rs`, so special md chars
like `_`, `*`, and `[` are escaped before being rendered.

## Testing

Created a file named `__somefile__` and tried to delete it, the name now
displays literally in the confirmation dialog instead of being rendered
as bold text:
<img width="339" height="206" alt="img"
src="https://github.com/user-attachments/assets/93e4e7d1-d5dc-45bb-9c08-2fe83c75aad2"
/>

Also added `test_delete_prompt_escapes_markdown_in_file_name` in
`project_panel_tests.rs` that verifies filenames with markdown special
characters render literally in the confirmation dialog.

Release Notes:

- Fixed file names containing markdown special characters (e.g.
`__somefile__`)
being rendered as formatted text in the file deletion confirmation
dialog.
