What changed

• feat: make icons CMS-editable and add footer logo (Icons not editable in Sveltia CMS Assets view — media_folder mismatch #79)

Approach

• Changed media_folder to /public and public_folder to / in public/admin/config.yml (Option B, author-chosen) so every committed asset under public/ — including the 16 SVG icons in public/icons/ — is visible and editable in the Sveltia CMS Assets view.
• Switched the Step and Card icon fields from widget: string to widget: image so editors pick an icon from the Assets library instead of typing a path. public_folder: / keeps the stored value root-relative (/icons/step-1.svg), so existing content and Astro rendering are unchanged (no regression).
• Added a logo image field to the Footer collection in config.yml, a logo: z.string() field to the footer schema in src/content.config.ts, and logo: /boucle-logo.png frontmatter in src/content/footer/footer.md.
• Rendered the non-animated boucle-logo.png in the footer of src/pages/index.astro above the "Made in" text, marked purely decorative (alt="", aria-hidden="true"), with a .footer-logo CSS rule.
• Updated the README CMS section to describe the Assets library / image-picker workflow instead of path typing.

Scope self-check:

• Task as stated: Option B media_folder + image widgets + decorative CMS-editable footer logo.
• Files I touched: public/admin/config.yml, src/content.config.ts, src/content/footer/footer.md, src/pages/index.astro, README.md.
• Lines I'm tempted to add but won't: none.
• Abstractions considered and rejected: none.
• Diff size: 5 files, +30/−13.
• Could it be smaller? no.
