feat: Add API Keys and Image Uploads support to Plummer dashboard/api

[kiyarose]

This PR introduces two major features to Plummer:

1. API Keys Management & Authentication:

   • Adds a new "API Keys" section to the admin dashboard allowing administrators to generate, view, and revoke API keys with granular permissions (create, read, update, delete) and optional expiry/host scoping.
   • Updates checkApiKeyAuth to seamlessly intercept and enforce Bearer tokens on /api/* endpoints. Token hashes are stored in KV using a apikey:<host>:<id> format, while the user uses an id.secret string allowing O(1) KV lookup.
   • All management endpoints like /api/keys strictly require core administrative Basic Auth.

2. Image Link Hosting & Uploads:

   • Adds an isImage toggle onto the link creation form in the admin dashboard, shifting the input to a file upload while disabling unnecessary fields like the destination URL.
   • Link payload creation is extended to handle multipart/form-data, ensuring a hard size limit of 5MB.
   • Image bytes are isolated and safely stored in the LINKIVERSE KV store mapped by image:<host>:<slug>.
   • The primary router correctly streams KV image data out with proper Content-Type mapping instead of forwarding requests to guest if type: 'image' is encountered.
   • src/index.js background scheduled link purge correctly cleans up any leftover KV image data when tombstoned images are purged.
