Rendering optimizations and function refactors

Handle `find_command` inside state itself -> `get_command_by_name`. Move tips to a seperate file for modularity. Pass the whole args to state instead of seperate args. Use const for float and confirmation prompt float sizes. Add the `longest_tab_length` to appstate struct so that it will not be calculated for each frame render use static str instead String for tips. Use function for spawning confirmprompt. Merge command list and task items list rendering a single widget instead of two. Remove redundant keys in handle_key. Optimize scrolling logic. Rename `toggle_task_list_guide` -> `enable_task_list_guide`
