Paulo Castellano 148a2f432f feat: AI image generation pipeline and post creation overhaul
Core changes:
- Replace Unsplash slide pipeline with gpt-image-2 via Laravel AI SDK.
  New AiImageClient builds prompts from a Blade template seeded by the
  workspace's ImageStyle enum, content language, brand color (mapped to a
  human-readable name via HexColorName helper) and brand description.
- Drop Template B from TemplateImageGenerator: every slide now renders as
  Template A (full-bleed photo + bottom gradient + white/grey overlay).
  Removes renderTemplateB, roundCorners, blendHex, ensureContrast and the
  closing-slide pipeline.
- StreamPostCreation creates the Post directly and dispatches
  PostCreationReady with post_id; the wizard kills its preview step and
  redirects straight to the post editor on completion. Finalize endpoint
  removed.
- New Workspace.image_style enum field with an 8-option visual picker
  shared by /workspaces/create and /settings/workspace/brand via a single
  BrandForm component (autofill is a prop). 8 sample webp thumbs ship
  under public/images/branding/image-styles/.
- Media items gain optional source ('ai'|'unsplash'|'giphy') and
  source_meta (recipe needed to regenerate AI images later); the gallery
  picker tags Unsplash/Giphy attachments.
- Brand-color autofill: new CssColorFrequencyExtractor parses every
  hex/rgb/hsl value in the homepage CSS, clusters perceptually similar
  shades in CIE LAB (Delta E 76 < 12), filters neutrals and returns the
  most frequent cluster. Solves Tailwind/utility-CSS sites where no
  semantic --primary variable is exposed.
- Credits: gpt-image-2 metered at 15 credits/image (low quality default).
- Layout: AuthSplitLayout right column is sticky/h-svh so the form
  textarea growth no longer stretches the marketing slider.
- i18n cleanup: localized labels follow the no-em-dash convention.
