chore: delete three functions nothing calls (#550)

src/base_classes/baseball.py       _get_baseball_display_text   45 lines
  src/web_interface/api_helpers.py   validate_request_params      22
  web_interface/blueprints/api_v3.py _validate_time_range         14

Each has exactly one occurrence across both repositories -- its own
definition. No decorator, no __all__, no getattr dispatch, nothing in
templates or JavaScript.

A fourth candidate was dropped after checking: _unshare_element_fonts in
src/common/sports_shared.py looked unreferenced, but eight scoreboard plugins
call SportsCore._unshare_element_fonts directly from their
test_element_text_colors.py, plus their own copies at runtime. It is live API.
The earlier reading came from a plugins checkout 84 commits behind main, which
is a good argument for re-verifying this kind of claim against a fresh tree
rather than trusting an earlier scan.

Full suite: 4,265 passed, 68 skipped.
