docs(rfc): correct AD-2/AD-5 and Appendix B to reflect ecosystem state

Three RFC drift corrections discovered during F3 implementation:

1. AD-5 icon rendering: corrected from "<i :class='i-tabler-X'>"
   utility-class pattern (which would require UnoCSS, not installed)
   to "@iconify/vue's <Icon> component with name='tabler-X' prop"
   (existing Crewli pattern producing real SVG output). The thin wrapper
   shipped in F3 B6 as apps/app/src/components/Icon.vue accordingly.

2. AD-2 theme architecture: corrected package reference from
   @primevue/themes@^4.5 (deprecated by PrimeFaces) to
   @primeuix/themes@^2 (the path now prescribed by PrimeVue 4's
   official install docs at primevue.org/vite/). Same maintainers,
   same API surface (definePreset, Aura preset, semantic tokens).
   F3 commit B1 already uses the corrected package.

3. Appendix B Aura theme token plan: updated import-path examples to
   @primeuix/themes and @primeuix/themes/aura accordingly.

Also updated:
- §6 F3 deliverables list: dependency line now reads @primeuix/themes@^2
  with a footnote linking to the B1 rationale.
- Appendix C Version Pinning Policy: separated @primeuix/themes from
  the primevue/^primevue/forms lockstep pin (independent release cadence).
- dev-docs/PRIMEVUE_COMPONENTS.md §3 (Data display): VIcon row updated
  to <Icon name="tabler-..." />; surrounding migration-spirit paragraph
  rewritten; §10 external-resources link relabeled to @primeuix/themes.

These are RFC drift corrections — the implementation in F3 (commits
B1, B2, B6 of this sprint) already uses the corrected packages and
import paths. This commit aligns the spec with reality so future
contributors don't reach for the deprecated/inaccurate documentation.

+classes were considered but not adopted (UnoCSS is not in the stack);

 uses `Listbox`, a card grid uses `DataView`, a navigation list uses
