Subject: [PATCH] test: impose tax on `__init__.py` (#28940)

Call it a new year's resolution.

`frappe/__init__.py` has grown crazy big over time and left unattended it will continue to grow.

This new ~test~ tax will require reducing 3 line per day (so ~1000 in a year) from 1st Jan 2025 onwards. I am offering a headstart of 50 days in this PR by moving ~150 lines: #28869
