Refactor UI elements for consistency and clarity

- Updated action buttons across multiple files to use icons (e.g., "Save" to "💾+", "Delete" to "X").
- Replaced "Cancel" button text with a left arrow (←) for a more intuitive navigation experience.
- Removed unnecessary action columns from tables to streamline the interface.
- Enhanced table rows to be clickable for better user interaction, redirecting to relevant management pages.
- Adjusted font sizes and styles in CSS for improved readability and aesthetics.
- Standardized back button functionality to use a left arrow across various pages.
