Move utils from ui to util (#6440)

Refactor: Extract UI utilities into beets/util

This PR decouples terminal/display utilities from beets/ui by moving
them into focused modules under beets/util. No user-facing behaviour
changes.

What moved where

Utility	From	To
colorize, uncolorize, color_len, color_split, ANSI constants
beets/ui/__init__.py	beets/util/color.py
colordiff, _field_diff, get_model_changes
beets/ui/__init__.py	beets/util/diff.py
indent, split_into_lines, print_column_layout,
print_newline_layout	beets/ui/__init__.py	beets/util/layout.py

|

Notable design change in layout.py

print_column_layout / print_newline_layout previously called
ui.print_() internally, creating a hard dependency on beets.ui. They
are now renamed to get_column_layout / get_newline_layout and
converted to generators, yielding lines instead of printing them.
The caller (display.py) is responsible for printing via ui.print_().

New public API

get_model_changes is introduced in beets/util/diff.py as the pure,
testable function for computing field-level diffs. show_model_changes
in beets/ui now delegates to it.

Tests

• Moved alongside the code: test/util/test_color.py,
  test/util/test_diff.py, test/util/test_layout.py.
• Removed duplicate ShowModelChangeTest from test/ui/test_ui.py —
  coverage is preserved in test/util/test_diff.py.
