Remote Reply: Use Interactivity API

[obenland]

Moves the Remote Reply "block" to using the Interactivity API for front-end rendering. Removes the block's dependency on React in the frontend.

Proposed changes:

• Removes remote-reply block from .prettierignore to accept formatting.
• Updates comments handling to load remote-reply through block processing rather than manual script enqueues.
• Updates Follow Me and Reactions block to standardize block registration using block.json.
• Moves remote-reply block to using Interactivity API to handle its functionality in the frontend.

Other information:

• Have you written new tests for your changes, if applicable?

Testing instructions:

• Test the block with a comment sent in from the Fediverse.
• Visit the post while being logged-out.
• Make sure modal operation, saving actor info, sending to instance for reply all still works.

build/remote-reply/block.json:11

• The block.json references a view.js module that isn’t present in the build. Add the missing view.js under build/remote-reply/ or adjust the configuration to point to the correct script.

"viewScriptModule": "file:./view.js",

build/remote-reply/block.json:12

• Setting viewScript to wp-api-fetch will only enqueue the core API fetch package, not your block’s frontend code. Either reference your actual view script or remove this entry if it’s not needed.

"viewScript": "wp-api-fetch",
