What kind of change does this PR introduce?

Documentation. Documents Instagram alt text: the image[].alt field on the public API create-post page, an alt text section on the Instagram provider page (images only, single and carousel, up to 1000 characters, not Reels or Stories), and the new posts:create --alt CLI option on the managing-posts and platform-examples pages.

Why was this change needed?

Companion to gitroomhq/postiz-app#2355 (Instagram providers forward media alt text as alt_text) and the postiz-agent --alt option. Without docs, users have no way to know the field is honored.

Other information:

Behaviour described here was verified end to end against real Instagram channels of both login kinds.

QA

1. Open the public API create-post page and confirm the alt field is listed on media objects with its Instagram note.
2. Open the Instagram provider page and confirm the alt text section states images only, 1000 characters, no Reels or Stories.
3. Open the CLI managing-posts and platform-examples pages and confirm the --alt examples match the option described in the postiz-agent README.

Checklist:

• I have filled in the QA section above with real steps to verify this change.

Walkthrough

The documentation describes the optional image alt field, provider-specific handling, and Instagram’s image alt text limits. It also documents the CLI --alt option and shows how to pair alt text with media URLs.
