MAINT Enable ruff rules: DTZ, N, T10, TID, YTT

[romanlutz]

Enable 5 additional ruff rule categories:

• DTZ: datetime timezone awareness (use timezone.utc everywhere, add _ensure_utc helper in memory_models to re-attach UTC to naive datetimes returned by SQLite)
• N: PEP 8 naming conventions (renamed camelCase variables to snake_case, noqa for intentional patterns like do_EOF, PyritException, Mock fixtures)
• T10: debugger calls (0 violations)
• TID: tidy imports (0 violations)
• YTT: sys.version checks (0 violations)

Pull request overview

Enables additional Ruff lint rule categories (DTZ, N, T10, TID, YTT) and updates the codebase accordingly, with a primary behavioral change being standardization on timezone-aware UTC datetimes and handling SQLite’s naive datetime round-tripping.

Changes:

• Standardize timestamp creation to datetime.now(tz=timezone.utc) across models, memory, and printers (DTZ).
• Rename variables/fixtures to PEP 8 naming and add targeted noqa for intentional patterns (N).
• Update unit/integration tests to use UTC-aware datetimes and to account for SQLite returning naive datetimes.

• The footer timestamp is now generated in UTC, but the printed value has no timezone indicator. Consider appending “UTC” (or formatting with %z / ISO-8601) so operators can interpret the time correctly.

        timestamp = datetime.now(tz=timezone.utc).strftime("%Y-%m-%d %H:%M:%S")
        print()
        self._print_colored("─" * self._width, Style.DIM, Fore.WHITE)
        footer_text = f"Report generated at: {timestamp}"
        self._print_colored(footer_text.center(self._width), Style.DIM, Fore.WHITE)

_ensure_utc is annotated as taking/returning datetime, but the implementation treats dt as possibly None (if dt is not None ... and return dt). This creates an inconsistent contract (and can confuse type-checkers); either make the parameter/return type Optional[datetime] or drop the None handling and assume a non-null datetime.

Suggested change

	def _ensure_utc(dt: datetime) -> datetime:
	"""
	Attach UTC tzinfo to a naive datetime (as returned by SQLite).
	Args:
	dt (datetime): The datetime to normalize.
	Returns:
	datetime: The datetime with UTC tzinfo attached if it was naive.
	def _ensure_utc(dt: Optional[datetime]) -> Optional[datetime]:
	"""
	Attach UTC tzinfo to a naive datetime (as returned by SQLite).
	Args:
	dt (Optional[datetime]): The datetime to normalize, or None.
	Returns:
	Optional[datetime]: The datetime with UTC tzinfo attached if it was naive, or None.

The footer timestamp is now generated in UTC, but the rendered string doesn’t indicate the timezone. This can be misleading in reports; consider including an explicit “UTC” suffix or using an ISO-8601 format with offset/Z.

Suggested change

	markdown_lines.append(f"*Report generated at {datetime.now(tz=timezone.utc).strftime('%Y-%m-%d %H:%M:%S')}*")
	timestamp_utc = datetime.now(tz=timezone.utc).isoformat().replace("+00:00", "Z")
	markdown_lines.append(f"*Report generated at {timestamp_utc}*")
