feat: shared rendering, footer, terms of service, git deployment, consistency fixes

Rendering consistency:
- Create shared renderProtocolPill() and renderCollectionPill() functions
  used everywhere: library, collection detail, user profile, picker
- All protocol/collection modules now look identical across all contexts
- Profile page collections and protocols use the same shared renderers
- Protocol grids wrapped in .protocol-grid for consistent spacing

New features:
- Footer with CC-BY 4.0 license link and Terms of Service link
- Terms of Service page stating admin reserves right to remove content
- CC-BY 4.0 default license for submitted content

Deployment:
- README now recommends git clone for initial deployment
- README documents git pull for updates without data loss
- All nav links use #protocols instead of #library

Bug fixes (from previous commits, re-applied to current codebase):
- Delete redirect: reset currentRoute guard so navigate works after delete
- #protocols routing instead of #library
- forked_from: null no longer shows as clickable link
- Source field suppressed when it duplicates author
- Collections say 'curated by' instead of 'authored by'
- Breadcrumb home click works from detail pages
- Search debounce and double-navigation guard

 **No default admin credentials exist.** A fresh deployment has an empty database. The first registration creates the admin account. Seed protocols are optional and must be explicitly loaded.

+To update an existing deployment without losing data, simply pull the latest code:
+
+```bash
+cd /path/to/protocol-droid
+git pull

+The SQLite database (`data/protocol_droid.db`) is not tracked by git and will be preserved across updates. The schema uses `CREATE TABLE IF NOT EXISTS` so existing tables are never overwritten.

-## Customizing the About page
-
-The About page is plain HTML in `frontend/index.html`, inside the `<section id="view-about">` element. To customize it for your deployment:
-
-1. Edit `frontend/index.html`
-2. Find the `<!-- ABOUT VIEW -->` section
-3. Modify the text, links, and sections as needed
-4. Upload the file to your server
-
-No rebuild step is needed — the HTML is served directly. The "Seed protocols" section at the bottom is automatically shown only to admin users, so you can leave it or remove it.
