Update demo replay validation and testing documentation

- Modified the autodev state to reflect the current testing phase and details of the new `jetson-e2e` tests.
- Enhanced the "How to Test" documentation to provide clearer instructions on the demo replay validation process, including video and tlog alignment steps.
- Updated architectural documentation to include the new demo replay operator flow and its dependencies.
- Documented the removal of deprecated auto-sync features and clarified the operator-facing UI for replay validation.
- Added new entries in the dependencies table for upcoming tasks related to the demo replay flow.

These changes improve clarity and usability for operators and developers working with the demo replay system.

+# Risk Register Template
+
+Use this template for risk assessment. Save as `_docs/02_document/risk_mitigations.md`.
+Subsequent iterations: `risk_mitigations_02.md`, `risk_mitigations_03.md`, etc.

+
+## Risk Scoring Matrix
+
+|  | Low Impact | Medium Impact | High Impact |
+|--|------------|---------------|-------------|
+| **High Probability** | Medium | High | Critical |
+| **Medium Probability** | Low | Medium | High |
+| **Low Probability** | Low | Low | Medium |
+
+## Acceptance Criteria by Risk Level
+
+| Level | Action Required |
+|-------|----------------|
+| Low | Accepted, monitored quarterly |
+| Medium | Mitigation plan required before implementation |
+| High | Mitigation + contingency plan required, reviewed weekly |
+| Critical | Must be resolved before proceeding to next planning step |

+## Risk Categories
+
+### Technical Risks
+- Technology choices may not meet requirements
+- Integration complexity underestimated

+- Security vulnerabilities in design
+- Data model cannot support future requirements
+
+### Schedule Risks
+- Dependencies delayed
+- Scope creep from ambiguous requirements
+- Underestimated complexity
+
+### Resource Risks
+- Key person dependency
+- Team lacks experience with chosen technology
+- Infrastructure not available in time
+
+### External Risks
+- Third-party API changes or deprecation
+- Vendor reliability or pricing changes
+- Regulatory or compliance changes
+- Data source availability
