refactor: reposition POST badge as button

Moved POST badge to align at the end of the input field and styled it as a button.

Changes:
- Changed flex container from items-start to items-end
- Removed nested div wrapper around input
- Styled POST badge as a button (btn btn-sm btn-warning)
- Used proper button padding and sizing
