Issue number: internal

What is the new behavior?

This pull request updates the color and background variables across many Ionic component styles to use new design system tokens, improving consistency and maintainability. It also temporarily skips several visual regression tests for the datetime component due to a known issue (FW-6769).

Design System Token Migration:

• Updated --color and --background variables in many components (e.g., card, card-title, list-header, item, segment, radio, select, textarea, input, checkbox, chip, datetime, item-options, searchbar) to use the new globals.$ion-text-default and globals.$ion-bg-surface-default tokens instead of older primitives. This change ensures consistent theming and easier future maintenance. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22]

Test Suite Maintenance:

• Temporarily skipped several E2E visual regression tests for datetime and item components, referencing TODO FW-6769, to prevent test failures while an upstream issue is addressed. [1] [2] [3] [4] [5]

There're some snapshots updates that seem to have no visible differences, so I would say its ok to accept the new ones.

Does this introduce a breaking change?
