Revert aggressive optimizations, apply conservative delay reductions

Reverted all previous optimization changes and re-applied only safe, conservative optimizations:
- Reduced drag/connect operation delays by removing redundant waits (450ms → 250ms, 350ms → 200ms)
- Reduced zoom/pan delays (200ms → 100ms, 100ms → 50ms)
- Reduced breakpoint test delays (300ms → 150ms)
- Reduced UI test delays (500ms → 200ms)
- Fixed DeleteConnectionBetweenEntryAndReturnNodes by waiting for nodes to be visible

All 48 tests pass (same as baseline). Time reduced from 2.29min to 2.04min (11% improvement, 15s saved).
