feat(folder): add commit reset action in git log

Add a "Reset to Here" context action for git log commit items in the folder page.

Show a reset dialog with branch, target commit, commit message, and reset mode details for soft, mixed, hard, and keep.

Disable reset when viewing a non-current branch filter and keep the action ordering under commit diff.

Add git_reset support across Rust commands, Tauri invoke registration, web handlers/routes, and frontend API/type bindings.

Add localized reset labels, mode descriptions, and toast messages across all supported languages.
