cclohmar e831fcf617 fix: resolve 7 critical security findings from code review
CR-1: Path traversal in createReceiptZip — validate image_path is within storage/
CR-2: Missing authz on EditExpense/UpdateExpense — verify event ownership
CR-3: OTP timing side-channel — use crypto/subtle.ConstantTimeCompare
CR-4: Logout doesn't invalidate session — moved to AuthHandler with Sessions.Delete()
CR-5: OTP reuse race condition — mutex lock around validate+delete
CR-6: Live credentials on disk — removed .env from disk entirely
CR-7: No TLS — documented as expected behind-proxy deployment

Additional:
- Removed stale github.com/expenseflow import path from auth.go
- Made EnvironmentFile optional (prefix with -) so .env is not required
- App runs and starts clean without any .env file
