Tokens issued before 'id' was added to the JWT payload pass signature
verification but cause a KeyError when endpoints access user['id'].
verify_token() now returns None for any token missing id/username/role,
triggering a 401 → the frontend interceptor clears localStorage and
redirects to /login so a fresh token is issued automatically.

- logger.py: note why log path uses abspath(__file__) instead of a relative path
- token.py: note why [7:] slice is safe (startswith already verified)
- ipcalc.py: explain /32 single-host and /31 RFC-3021 point-to-point special
cases; explain why (~netmask) must be masked with 0xFFFFFFFF (Python ~int
returns a negative arbitrary-precision value, not a 32-bit unsigned integer)
- notes.py: document the module-level _table_ready flag lifetime; explain why
tzinfo is stripped before passing datetime to mysql-connector
- admin.py: document the module-level _tables_initialized flag lifetime

- Fix AttributeError crash on empty request body in md5, hasher, textdiff,
jwtdecoder, timestamp, passwordgen (get_json without silent=True / or {})
- Fix memory exhaustion in ipcalc: replace list(network.hosts()) with direct
arithmetic — safe for /8 and larger networks
- Fix O(1M) loop in cronexplainer.get_next_runs: rewrite to skip by
month/day/hour instead of iterating every minute
- Fix connection leak in notes.ensure_table: add try/finally around conn.close
- Fix admin._ensure_tables / notes._ensure_table running DDL on every request:
guard with module-level flags (_tables_initialized, _table_ready)
- Fix update_website returning 200 when no row matched; delete_website returning
success when nothing was deleted; add rowcount checks for both
- Add role validation in admin create_user / update_user (_VALID_ROLES guard)
- Add delimiter length guard in csvviewer (csv.reader requires single char)
- Fix loremipsum: wrap int(count) in try/except ValueError → 400 response
- Fix auth/token: use auth_header[7:] instead of fragile .replace()
- Fix app.py: remove duplicate import sys; cache DB liveness check with 30s TTL
to avoid a new TCP connection on every frontend page load; move api/setup
path guard before DB check
- Replace FileHandler with RotatingFileHandler (5 MB / 3 backups) in logger;
fix relative log paths to absolute paths anchored to __file__
- Wrap all DB connections in try/finally conn.close() throughout admin and notes
