## **Description**

<!--
Write a short description of the changes included in this pull request,
also include relevant motivation and context. Have in mind the following
questions:
1. What is the reason for the change?
2. What is the improvement/solution?
-->

This PR addresses two issues related to the Card feature and onboarding
experience:
- Delegation refresh issue: After completing a successful delegation,
some data were not properly updated when navigating back to the CardHome
screen. This fix ensures all relevant data refresh correctly to reflect
the latest state.
- KYC WebView permissions: Removed a property that was preventing the
KYC WebView during onboarding from requesting camera and microphone
access, restoring the expected behavior for KYC verification.

## **Changelog**

<!--
If this PR is not End-User-Facing and should not show up in the
CHANGELOG, you can choose to either:
1. Write `CHANGELOG entry: null`
2. Label with `no-changelog`

If this PR is End-User-Facing, please write a short User-Facing
description in the past tense like:
`CHANGELOG entry: Added a new tab for users to see their NFTs`
`CHANGELOG entry: Fixed a bug that was causing some NFTs to flicker`

(This helps the Release Engineer do their job more quickly and
accurately)

> [!NOTE]
> Adds a post-delegation delay and cache clear to refresh Card data,
consolidates loading/navigation handling, removes token priority update,
and re-enables KYC camera/mic prompts.
> 
> - **Card — Spending Limit
(`app/components/UI/Card/Views/SpendingLimit/SpendingLimit.tsx`)**:
> - Aggregate loading state via `isProcessing` + `isDelegationLoading`
(`isLoading`); block back/cancel while loading; update button
`disabled`/`loading` states.
> - On confirm: validate SDK (error toast if missing), submit
delegation, wait 3s,
`dispatch(clearCacheData('card-external-wallet-details'))`, show success
toast, then navigate back.
> - Remove token priority update flow and related utilities; simplify
logic.
> - **Tests (`SpendingLimit.test.tsx`)**:
> - Remove token-priority mocks/tests; adjust expectations to await 3s
delay, cache clear, success toast, and navigation.
>   - Add/modify loading and navigation blocking/cancel behavior tests.
> - **Onboarding — KYC WebView
(`app/components/UI/Card/components/Onboarding/KYCWebview.tsx`)**:
> - Remove `mediaCapturePermissionGrantType` to allow camera/microphone
permission prompts.
