Add protocol mapper switch sanity test and correct existing switch errors

[Copilot]

Protocol switches could reference values absent from their preceding mapper, causing undefined dispatch behavior. Add CI validation to detect these mismatches across protocol JSON files.

• Validation: Traverse protocol types, resolve mapper aliases, and verify switch cases against previously defined mapper values.
• Diagnostics: Log switches whose comparison field cannot be resolved; fail on known mapper mismatches.
• Data fixes: Correct existing PC and Bedrock mapper/switch inconsistencies and regenerate affected protocol JSON.

if (!mapper.has(value)) {
  issues.push(`${location}: ${compareTo} -> ${value}`)
}

• Fixes Add sanity check of sorts to prevent switching on undefined map value #1285

Hmm. Thinking about it it would make sense to put this into protodef-validator itself. But for now this seems like good stopgap fixing present protocol def bugs
