* feat(telegram): add spoiler tag support
Render markdown ||spoiler|| syntax as <tg-spoiler> tags in Telegram HTML output.
The markdown IR already parses spoiler syntax, but the Telegram renderer was
missing the style marker. This adds the spoiler marker to renderTelegramHtml().
Fixes spoiler text appearing as raw ||text|| instead of hidden text.
* fix: enable Telegram spoiler rendering (#11543) (thanks @ezhikkk)

Unify style and link closing in render.ts to use LIFO order across
both element types, fixing cases where bold/italic spans containing
autolinks produced invalid HTML like <b><a></b></a>.
