chore: cleanup code smells from truecourse audit (#74)

* chore: cleanup code smells from truecourse audit

Remove unused React imports (4 files), consolidate duplicate imports
(5 files), delete unused getEnrichedPropdatesList export, sanitize error
messages in 4 API routes (no longer leak internal exception details),
ignore .truecourse/ analyzer output.

All findings verified manually; ~90% of truecourse's 6382 flags were
false positives (Web3 addresses flagged as secrets, Three.js mutation,
intentional fire-and-forget promises, etc.). Only validated changes
applied.

Not using the tool, removed its output dir too.
