telemetry(amazonq): add fields for code fix events

[ctlai95]

Problem

Need to understand:

• How many users are using fix feature from /review (not auto-review)
• How many fixes were generated/applied for each scanJob
• How many code fix requests were unable to generate a fix

Solution

• Add flag autoDetected to be able to filter out auto-review findings
• Add flag includesFix to be able to see fix requests that generated no fixes
• Add codewhispererCodeScanJobId to associate a fix action with a specific scan that produced the finding

---

• Treat all work as PUBLIC. Private feature/x branches will not be squash-merged at release time.
• Your code changes must meet the guidelines in CONTRIBUTING.md.
