Task 626: Fix Stale Hardcoded Count Assertions in E2E Tests

Status: DONE

Problem

Several E2E tests use exact hardcoded counts (e.g., toBe(15) for ADR rows, toBe(13) for ideas rows) that will break as soon as content is added. These are maintenance traps that cause false test failures unrelated to actual bugs.

Solution

Replace fragile exact-count assertions with threshold-based assertions (toBeGreaterThanOrEqual) where the exact count is not semantically meaningful. Keep exact counts only where they validate specific structural invariants (like 5 episode tabs).
