Upgrades antd 5.26 -> 6.5 (and @ant-design/icons -> 6) across the frontend.
Theme-safe: the getDesignToken -> allowedAntdTokens -> ConfigProvider/Emotion
bridge works on v6 with no token loss (only cosmetic box-shadow recomputation).
Adds theme characterization tests that lock the full computed token set for
light and dark so any future token rename/removal fails loudly.
Key changes:
- Theme bridge: coerce boolean `cssVar` (removed from v6 ThemeConfig) to the
object form.
- Wrappers/app: Select (dropdownAlign removed; showSearch/tokenSeparators union
handling), Tooltip/Popover/DropdownContainer styles.body -> styles.container,
Steps.Step -> items, Popover/Tooltip/Dropdown visible/onVisibleChange ->
open/onOpenChange, Dropdown overlay -> menu, Pagination size="default"
removed, .ant-tooltip-inner -> .ant-tooltip-container and
.ant-select-selector -> .ant-select-content in styled CSS.
- Fixes a real regression the tests caught: antd v6 Tag overwrites its `icon`
prop's inline style, dropping Label icon colors; fixed by wrapping the icon.
- Deps: remove unused @rjsf/antd (pinned antd 5); bump @rjsf/core/utils/
validator-ajv8 to v6; pin jsonforms-antd-renderers to antd 6 via overrides.
- Test env: replace the `MessageChannel = undefined` stub with a polyfill
(antd v6's scheduler needs the constructor).
- Update test-DOM assertions across suites for v6 class/structure renames.
