Fix: NoneType error in normalize_will when others_inputs is None

When deleting old transactions and clicking Check, task_phase1 would fail
with 'NoneType object has no attribute get' error in WillItem.normalize_locktime.

Root cause: In Will.normalize_will (will.py:150), the parameter others_inputs
defaults to None. At line 151, a local variable 'others_input' is created with
a safe default value (empty dict). However, lines 179 and 184 still used the
original 'others_inputs' parameter instead of the safe local variable, causing
the error when calling .get() on None.

Fix: Use the safe 'others_input' variable instead of the raw parameter in
lines 179 and 184.

Also added:
- Traceback logging to on_error_phase1 so future errors include full call stack
- Debug logging in update_all to log willitems state before processing
- Comprehensive test (test_e5_build_with_real_wallet_heirs_and_utxos) that
  reproduces the exact scenario from the user's karen7 wallet
