[TASK] Improve Transaction Flow and Clarify Function of Shielded Pools on Hubble Bridge

Proposed Solution

To improve the user's understanding of making a transaction on Hubble Bridge, the following tasks are proposed to address the issue:

[ ] Replace the term Bridging Token with Shielded Pool on the bridge card for deposit, transfer, and withdrawal flow to improve the understanding of their shielded assets, which is the term used in the user's notes account table.
[ ] Add tooltip for Shielded Pool (shown below) to better inform users.
[ ] Add alert component in the shielded pool selection card in deposit, transfer, and withdrawal to give users more context about the action.
[ ] Update search box copy to 'Search pool or enter contract address'.
[ ] Remove irrelevant token display (as shown below: AGOR, WETH etc.) to the pool selection card to mitigate confusion. We should only display deployed pools in the list (whether available or unavailable).
[ ] Remove the section on 'Don't see your asset? Try another account or wallet' on pool selection card in favor of alert component. This only needs to appear in the token selection card.
