RNTester's RCTBlobManagerTests fail on main: setUp sets the bridge key that #59250 removed #59597

Description

#59250 removed @synthesize bridge = _bridge; from RCTBlobManager.mm. RNTesterUnitTests/RCTBlobManagerTests.m still sets that property by key in its setUp, [_module setValue:nil forKey:@"bridge"]; (L30), so every test in the class fails with NSUnknownKeyException before it runs: testCreateFromParts, testRemove, testResolve, testResolveMap and testResolveURL. No CI job runs RNTester's iOS unit tests (#59596), so nothing reports it.

Steps to reproduce

1. In packages/rn-tester: bundle install, then bundle exec pod install.
2. xcodebuild test -workspace RNTesterPods.xcworkspace -scheme RNTester -configuration Debug -destination <an iOS device or simulator> -only-testing:RNTesterUnitTests/RCTBlobManagerTests

Expected: the five tests pass.
Seen: each fails at setUp's line 30.

I ran it on an iPhone 12 Pro Max (iOS 27.0.1, Xcode 27.1, macOS 27.0.1) at main 42ba24a; RCTBlobManagerTests.m and RCTBlobManager.mm are unchanged from there to c12d0b3.
