Feat/trust lookup history

[Devadakene]

This PR closes #445

Description

This pull request adds a local, capped, and de-duplicated recent lookups history to the Trust Score page, turning repeated Stellar address checks into a single click.

Key Features

1. Lookup History Persistence:

   • Persists lookups locally using the existing useLocalStorage hook under the key 'credence:recent-lookups'.
   • Capped at the last 5 entries, de-duplicated, and sorted with the most recent lookup at the top.
   • Cleans up and filters any corrupt or invalid localStorage payloads on load.

2. Keyboard-Accessible Recent Lookups UI:

   • Renders a control below the AddressInput presenting the recent lookups.
   • Utilizes native <button> elements to guarantee keyboard focusability and activation (via space/Enter).
   • Dynamically respects the addressDisplay settings ('short'/'full'/'friendly') from SettingsContext. If set to 'friendly' and the entry matches the currently connected wallet, it renders 'My Wallet'.
   • Incorporates a "Clear history" button to easily reset the lookup list.
   • The control is hidden automatically if the history is empty.

3. URL & Active State Integration:

   • Clicking a recent lookup button pre-fills the address input, updates the URL ?address= parameter for query parameter synchronization, and triggers the score lookup immediately.

Files Modified

• src/pages/TrustScore.tsx: Added recent lookups state, logic, event handlers, and UI markup.
• src/pages/TrustScore.css: Styled the lookup history container, list, action buttons, and clear button with accessible focus rings and hover transitions.
• src/pages/TrustScore.test.tsx: Added comprehensive RTL tests verifying capping/de-duplication ordering, clear actions, selection-triggered lookups, formatting modes, and corrupt fallback handling.
