from_format crashed with a raw AttributeError on every ordinal token, instead of either parsing or raising the regular ValueError("Unsupported token: ..."):

>>> pendulum.from_format("7 Juni 1982", "Do MMMM YYYY", locale="de")
AttributeError: 'NoneType' object has no attribute 'values'   # de has no ordinal suffixes
>>> pendulum.from_format("2nd 1982", "Qo YYYY", locale="en")
AttributeError: 'NoneType' object has no attribute 'values'   # Qo/Mo/DDDo are None in _LOCALIZABLE_TOKENS

This makes from_format accept what format() emits:

• Do in a locale without a custom.ordinal table (de, bg, ru, pl, uk, …) accepts plain digits — exactly what format() emits there, since Locale.ordinalize falls back to the plain number.
• Mo, Qo and DDDo get real parsing: the \d+<suffix> candidates built from the locale's ordinal table, populating month / quarter / day-of-year — all three fields are already consumed downstream.

>>> pendulum.from_format("7 Juni 1982", "Do MMMM YYYY", locale="de")
1982-06-07 00:00:00+00:00
>>> pendulum.from_format("2nd 1982", "Qo YYYY", locale="en").quarter
2
>>> dt.format("DDDo YYYY")    # round-trips
'158th 1982'

• The tokens that are deliberately not parseable (do, e, eo, Wo, wo) now raise ValueError: Unsupported token: … — the exception _replace_tokens was designed to raise — instead of AttributeError leaking from locale.translation(None).values().

Fixes #1074.

Verification (system Python 3.13; python-dateutil/tzdata/time-machine wheels on the path, nothing installed):

• 9 new tests in tests/datetime/test_from_format.py (ordinal round-trips across locales, the plain-digit Do fallback, parametrized ValueError for the five unsupported tokens): all fail on master@e06dace, all pass with this change.
• tests/datetime, tests/formatting, tests/parsing, tests/date, tests/time, tests/interval: 1102 passed with the fix; tests/test_main.py has one pre-existing date-sensitive failure (Europe/Paris offset), confirmed identical on unpatched master.
