`export_transactions` CSV crashes on "Aktien erhalten" event

Bug: export_transactions CSV crashes on "Aktien erhalten" event

Description

Running pytr export_transactions with CSV format crashes with an AttributeError when the timeline contains an "Aktien erhalten" (shares received) event. JSON export works fine.

Steps to reproduce

pytr export_transactions

Expected behavior

CSV file is exported, unknown event types are skipped or handled gracefully.

Actual behavior

The command crashes with the following traceback:

21:44:23 Ignoring unknown event "AI & Big Data USD (Acc) Aktien erhalten (9e81acd0-3fe1-409b-abfd-96f26088eeb0)"
Traceback (most recent call last):
  File ".../bin/pytr", line 12, in <module>
    sys.exit(main())
  File ".../pytr/main.py", line 533, in main
    [Event.from_dict(item) for item in events],
  File ".../pytr/event.py", line 462, in from_dict
    note = cls._parse_card_note(event_dict)
  File ".../pytr/event.py", line 790, in _parse_card_note
    if eventTypeStr.startswith("card_"):
       ^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'startswith'

Root cause (hypothesis)

_parse_card_note in event.py (line 790) calls .startswith() on eventTypeStr without checking if it's None first. The "Aktien erhalten" event type seems to return None for this field.

Environment

• OS: Linux
• pytr version: latest
• Login method: web login

Workaround

JSON export works fine. The data can be converted to CSV manually via pandas.

[RealCLanger]

The bug report suggests an outdated version of pytr. The current code reads:

eventTypeStr = event_dict.get("eventType", "")
if eventTypeStr.startswith("card_"):

So this should not happen. I recommend to update the pytr installation, e.g. through

pip install --upgrade pytr

and try again. However, the "Aktien erhalten" event seems unsupported. If you could share the json snippet, we could try to add real support for it.
