components: draw the shared Compose vocabulary from floret-kit

Phase 4 (components). Agendula now sources its grouped-row primitive
(GroupedSurface/GroupedRow + Position/positionOf), InlineTextField, OptionCard,
and pastelize() from the kit's components module instead of its own ui/common
copies. These were Agendula's versions, taken as the canonical family reference
(design sign-off); Agendula keeps its own identity chips (ListColorChip/
ListNameChip task glyph, PriorityChip) which now import the shared pastelize.

- Delete app copies of GroupedList/InlineTextField/OptionCard; drop the local
  pastelize from ListChip. Repoint all imports (cross-package + same-package +
  one inline FQN) to de.jeanlucmakiola.floret.components. Submodule re-pinned.

Clean composite build + tests + lintDebug + debug assemble green.
