fix: fetch proton from remote git repo and pin commit in buf.gen.yaml

[ravisuhag]

Summary

• Fetch proton proto definitions from remote GitHub repo instead of requiring a local directory
• Pin proton commit hash in buf.gen.yaml for reproducible code generation
• Upgrade chronicle to 0.5.4 and remove unused store/postgres.go function
• Remove vendored gen/buf/validate/validate.pb.go (now fetched from remote)

Test plan

• Run make proto and verify proto generation works from remote
• Run make build to confirm compilation
• Run make test to verify no regressions
