Related wish: W43 – Allow editors to subscribe to community wishes

Problem

Having just gone through every singe wish doing the migration, I noticed we have a clunky, unstructured means of making notes about a wish visible to everyone reading it.

Examples:

• Banner at the top of https://meta.wikimedia.org/wiki/Community_Wishlist/W217
• Message embedded in the description at https://meta.wikimedia.org/wiki/Community_Wishlist/W28
• https://meta.wikimedia.org/wiki/Community_Wishlist/W84
• …

In addition, these updates don't notify the users. They may never be informed an update even happened.

Proposal

Add a new section, "Updates", where Community Wishlist managers can help add context to the wish, explain decision-making (such as why a wish was declined), or to announce general updates on the wish.

r1205012 should be reworked so that the automatic logged updates (what we added for T411841) get copied to the "Updates" section as {{int: …}} messages (so they're always translated). In the form, we'd have a textarea input for Wishlist managers to write a new free-form update, and we send out the notification itself in the same way we did for T411841. If there's a structured change (i.e. status change) that happens in the same edit, they'd share the same comment in the "Updates" section.

Imagine an updates section that looks like:

• [20:44, 5 October 2025] Wish created --WishProposer (talk)
• [18:42, 10 October 2025] Status changed to "In progress" -- MusikAnimal (WMF)
• [2:10, 20 October 2025] Add to focus area "Template recall and discovery" CParle (WMF)
• [15:47, 5 November 2025] Status changed to "Done". Hello everyone! We are proud to announce this was has been completed. Thanks to everyone who helped make this wish come true. KSiebert (WMF)

Where each comment is presented as a bulleted item prefixed with a timestamp. We're sending out the notifications ourselves (as opposed to relying on DiscussionTools to do it via signed comments), so we can format the list however we'd like.
