Summary

Labels transcribe-stream-1 as Preview everywhere the docs present it. This was requested by NaturalHG. It follows the patterns the repo already uses for previews and betas (Drama 3 preview, the migration guide's Beta tag).

• Sidebar. The 4 realtime pages get tag: "Preview" in their frontmatter: the guide, the WebSocket reference and the two cookbooks.
• Page note. Each of those pages gets one <Note>: "transcribe-stream-1 is in preview." It does not mention pricing.
• Model mentions. Places that name the model get a "(Preview)" suffix, the same way "(recommended)" is used:
  • the models overview row;
  • the pricing row, which now reads transcribe-stream-1 (Realtime ASR, Preview); prices are unchanged;
  • the capabilities sentence;
  • the Realtime vs File table and the model header row in the reference;
  • the AsyncAPI model header description (the enum and default are unchanged);
  • the five realtime entries in llms.txt.

Note for reviewers: #270 launched the model framed as GA ("No longer preview") and removed the earlier preview notes. This PR brings the Preview label back, at product's request. Please confirm the intended status with the #270 author before merging. Gating behaviour is unchanged.

Checks:

• prettier passes on the files that were clean before. Three files already failed prettier --check on main, and this PR adds no new drift to them.
• All changed MDX compiles, and @asyncapi/parser reports 0 errors and 0 warnings.
• No Chinese characters and no internal names.
• mint broken-links hung offline on the authoring machine, so it was not run there. CI or Mintlify validation covers it.
