Update health endpoint and refine test documentation

- Modified the health endpoint to return "None" for AI availability when inference is not initialized, improving clarity on system status.
- Enhanced the test documentation to include handling of skipped tests, emphasizing the need for investigation before proceeding.
- Updated test assertions to ensure proper execution order and prevent premature engine initialization.
- Refactored test cases to streamline performance testing and improve readability, removing unnecessary complexity.

These changes aim to enhance the robustness of the health check and improve the overall testing framework.

+- If user picks A → apply fixes, then re-run (loop back to step 2)

+- If user picks B → return failure to the autopilot

+
+**Any test skipped** → this is also a **blocking gate**. Skipped tests mean something is wrong — either with the test, the environment, or the test design. **Never blindly remove a skipped test.** Always investigate the root cause first.
+
+#### Investigation Protocol for Skipped Tests
+
+For each skipped test:
+
+1. **Read the test code** — understand what the test is supposed to verify and why it skips.
+2. **Determine the root cause** — why did the skip condition fire?
+   - Is the test environment misconfigured? (e.g., wrong ports, missing env vars, service not started correctly)
+   - Is the test ordering wrong? (e.g., a fixture in an earlier test mutates shared state)
+   - Is a dependency missing? (e.g., package not installed, fixture file absent)
+   - Is the skip condition outdated? (e.g., code was refactored but the skip guard still checks the old behavior)
+   - Is the test fundamentally untestable in the current setup? (e.g., requires Docker restart, different OS, special hardware)
+3. **Try to fix the root cause first** — the goal is to make the test run, not to delete it:
+   - Fix the environment or configuration
+   - Reorder tests or isolate shared state
+   - Install the missing dependency
+   - Update the skip condition to match current behavior
+4. **Only remove as last resort** — if the test truly cannot run in any realistic test environment (e.g., requires hardware not available, duplicates another test with identical assertions), then removal is justified. Document the reasoning.
+
+#### Categorization
+
+- **explicit skip (dead code)**: Has `@pytest.mark.skip` — investigate whether the reason in the decorator is still valid. Often these are temporary skips that became permanent by accident.
+- **runtime skip (unreachable)**: `pytest.skip()` fires inside the test body — investigate why the condition always triggers. Often fixable by adjusting test order, environment, or the condition itself.
+- **environment mismatch**: Test assumes a different environment — investigate whether the test environment setup can be fixed.
+- **missing fixture/data**: Data or service not available — investigate whether it can be provided.
+
+After investigating, present findings:
+
+```
+══════════════════════════════════════
+ SKIPPED TESTS: K tests skipped
+══════════════════════════════════════
+ 1. test_X — root cause: [detailed reason] → action: [fix / restructure / remove + justification]
+ 2. test_Y — root cause: [detailed reason] → action: [fix / restructure / remove + justification]
+══════════════════════════════════════
+ A) Apply recommended fixes, then re-run
+ B) Accept skips and proceed (requires user justification per skip)
+══════════════════════════════════════
+```
+
+Only option B allows proceeding with skips, and it requires explicit user approval with documented justification for each skip.
