perf: speed up bottom sheet animations to 150ms (#20692)

## **Description**

Improves bottom sheet responsiveness by reducing animation duration from
`300ms` to `150ms`. This makes interactions feel 2x faster while
remaining smooth and within industry standards (150-300ms range).

**Why this change:**
- Current 300ms feels slightly sluggish for frequent interactions
- 150ms strikes the optimal balance between speed and smoothness
- Aligns with modern UI expectations for responsive interactions

**Technical change:**
- Updated `DEFAULT_BOTTOMSHEETDIALOG_DISPLAY_DURATION` constant
- Changed from `AnimationDuration.Regularly` (300ms) to
`AnimationDuration.Fast` (150ms)
- Single line change in
`/app/.../foundation/BottomSheetDialog/BottomSheetDialog.constants.ts`

## **Manual testing steps**

```gherkin
Feature: Faster bottom sheet animations

  Scenario: User opens and closes bottom sheets
    Given the user is on the wallet home screen
    When the user opens account selector or network selector
    Then the bottom sheet should animate up in 150ms (noticeably faster than 300ms)
    When the user dismisses the sheet by swiping down or tapping outside
    Then it should animate down in 150ms
    
  Scenario: User interacts with wallet actions
    Given the user is on the wallet home screen
    When the user taps "Buy & Sell" or any wallet action button
    Then the wallet actions bottom sheet should appear quickly with 150ms animation
    
  Scenario: User connects to a dApp
    Given the user is browsing a dApp
    When the dApp requests connection
    Then the account connect bottom sheet should animate up smoothly in 150ms
```

## **Screenshots/Recordings**

### **Before**
300ms animation (`AnimationDuration.Regularly`)

### **After**
150ms animation (`AnimationDuration.Fast`) - 2x faster, more responsive
feel
