8e9a0c367a fix: replace os.environ direct assignment with monkeypatch.setenv in test fixtures
Prevents environment variable leaking between tests. All DATA_DIR,
JWT_SECRET_KEY, and SCRIPT_TIMEOUT assignments in fixtures now use
monkeypatch.setenv() which auto-reverts after each test. Removes
manual os.environ.pop() cleanup lines.

1b3acce7e9 fix: replace substring table access check with word-boundary regex
Replace substring matching with word-boundary regex in query endpoint's
table access validation. Prevents false positives where short table names
like 'id' would block any query containing the word. Uses re.escape() to
safely handle special characters in table names.

- Import re module at top
- Use regex pattern with word boundaries (\b) for matching
- Add tests to verify no false positives and proper blocking

3321d2e266 security: reduce JWT expiry to 24h and add jti claim
Tokens previously lasted 30 days with no revocation path. Expiry is now
24 hours and every token carries a unique jti (UUID hex) to support future
revocation checks.

23ae6a602c security: harden query endpoint SQL blocklist and disable external access
Expand blocked keywords to cover parquet_scan, read_csv_auto, query_table,
iceberg_scan, delta_scan, call, URL schemes (http/https/s3/gcs), and
additional file-scan functions. Set enable_external_access=false on the
non-read-only analytics connection path. Add three new tests covering
parquet_scan, read_csv_auto, and query_table blocking.

4aa97c23d2 fix: raise RuntimeError on missing JWT_SECRET_KEY in non-test environments
Prevents production deployments from silently using a hardcoded default
secret. TESTING=1 still resolves to a built-in test key so the existing
test suite is unaffected. Adds a test that verifies the RuntimeError is
raised when neither JWT_SECRET_KEY nor TESTING is set.
