🔧 Restore PRs #14348 and #14352 that were reverted by PR #14347 (#14359)

## Problem

**CRITICAL:** Two PRs were accidentally reverted when PR #14347 "Prevent
csv export injections" was merged:

1. **PR #14348** "[Page Layout] - Review Refactor" - ✅ **RESTORED**
2. **PR #14352** "Fix wrong path used by backend" - ✅ **RESTORED**

## Root Cause Analysis

During the merge of PR #14347, there was a complex merge conflict with
PR #14352 "Fix wrong path used by backend". The merge commit
`324d7204bb` in the PR #14347 branch brought in changes from PR #14352,
but during the conflict resolution, **BOTH PR #14348 and PR #14352's
changes were accidentally overwritten**.

## What This PR Restores

This PR restores **BOTH** PRs by cherry-picking their commits:

### ✅ PR #14348 Changes Restored:
- `GraphWidgetRenderer.tsx` - was deleted, now restored
- `WidgetRenderer.tsx` - was missing, now restored  
- `SettingsPageLayoutTabsInstanceId.ts` - was deleted, now restored
- `useUpdatePageLayoutWidget.ts` - was renamed back, now restored with
correct name
- Multiple test files that were deleted
- Several hook files that were renamed/reverted
- File renames: `usePageLayoutWidgetUpdate.ts` →
`useUpdatePageLayoutWidget.ts`
- Hook refactoring and test file organization
- Page layout component improvements

### ✅ PR #14352 Changes Restored:
- **Types moved to twenty-shared:**
  - `packages/twenty-shared/src/types/AppBasePath.ts` ✅ RESTORED
  - `packages/twenty-shared/src/types/AppPath.ts` ✅ RESTORED
  - `packages/twenty-shared/src/types/SettingsPath.ts` ✅ RESTORED
- **Navigation utilities moved to twenty-shared:**
- `packages/twenty-shared/src/utils/navigation/getAppPath.ts` ✅ RESTORED
- `packages/twenty-shared/src/utils/navigation/getSettingsPath.ts` ✅
RESTORED
- **200+ import statements updated** across the codebase to use
twenty-shared
- **Old type files deleted** from twenty-front/src/modules/types/

## Evidence of Complete Restoration

**Before (reverted state):**
- ❌ Types were in `packages/twenty-front/src/modules/types/`
- ❌ Page layout files missing
- ❌ Hook files incorrectly named

**After (this PR):**
- ✅ Types correctly in `packages/twenty-shared/src/types/`
- ✅ All page layout files restored
- ✅ Hook files correctly named
- ✅ All import statements updated

## Verification

**Total changes:**
- PR #14348: 36 files changed, 863 insertions(+), 442 deletions(-)
- PR #14352: 243 files changed, 492 insertions(+), 461 deletions(-)
- **Combined: 279 files changed, 1355 insertions(+), 903 deletions(-)**

## Impact

This completely restores both PRs that were accidentally lost, ensuring:
1. Page layout refactoring work is back
2. Type organization and path utilities are correctly in twenty-shared
3. Backend email paths work correctly again
4. No functionality is lost

Fixes the reversion caused by the merge conflict in PR #14347.
