Add the ability to filter commits by showing an input field in the commit panel, similar to the search functionality.
### Is your feature request related to a problem? Please describe. Hi team, I would find it very useful to not only search for commits, but also filter them (as described in https://github.com/jesseduffield/lazygit/blob/master/docs/Searching.md). Do you think it would be feasible? ### Describe the solution you'd like Pressing `<c-f>` (or other) in the commit panel would show an input (like "Search" when pressing `/`), and anything that's typed in it would filter the commits accordingly. ### Additional context <img width="796" height="478" alt="Image" src="https://github.com/user-attachments/assets/b398ffab-be46-4280-a1aa-15f835acda07" /> <!-- You may be able to add your desired feature with a custom command.
