docs: remove the automations module

[paulocastellano]

Summary

Follows trypostit/trypost#333, which removed the Automations module end to end. This clears everything the docs still said about it.

Deleted — knowledge-base/automations/{introduction,triggers-and-nodes,variables,monitoring}.mdx and the Automations nav group in docs.json.

Rewritten references, each checked against origin/main of the app:

File	What changed
knowledge-base/webhooks.mdx	created_via is now web, api, mcp, or null — CreatedVia has no Automation case. Dropped the intro contrast with the automation Webhook node, the automation-created-post sentence, and two FAQ accordions.
self-hosting/production.mdx	The four automation:* rows are gone from the scheduler table (routes/console.php no longer registers them), plus the queue bullet, the cron warning, and the Horizon / Scheduler checklist rows. Second commit puts webhooks back in the queue list — it was the one remaining Horizon supervisor the list didn't name.
self-hosting/installation.mdx	Redis, Horizon and Scheduler rows reworded.
self-hosting/configuration.mdx	QUEUE_CONNECTION says webhooks instead of automations. TRYPOST_ALLOW_PRIVATE_NETWORK drops RSS — #333 made the same edit to the config comment in config/trypost.php, and on main SafeHttpFetcher serves webhooks, URL media fetches, brand autofill and link cards.
self-hosting/upgrading.mdx	Duplicate-account merge no longer claims to move automation targets.
knowledge-base/plans-and-billing.mdx	Automations out of the included-features row.
knowledge-base/social-accounts.mdx	Reconnect no longer promises to keep an account's place in your automations.

Deliberately kept

automations_rewritten stays in the upgrading.mdx log sample. A commit inside #333 briefly made the 2026_08_21_130941_add_workspace_platform_identity_unique_to_social_accounts_table migration skip its automation repointing, but review reverted it to exactly what production ran — it still reads DB::table('automations'), and the create migrations were kept. Anyone crossing that version still sees the key in their logs.

No redirects

The four deleted pages will 404. Decided against a redirects block in docs.json.

Not included

Two pre-existing drifts spotted while diffing against the app, left for a separate PR: production.mdx never listed posts:check-upcoming-connections (every 15 min), and CLAUDE.md still calls social:refresh-expiring-tokens hourly when it runs every 15 minutes.

Test plan

• grep -rni automa over the whole repo (including .md / .json) returns only automations_rewritten and unrelated uses of "automatically"
• No leftovers under the module's other vocabulary either: vue-flow, codemirror, unovis, simplepie, rss, the node names, dry-run, invocation, and the "Beta" pill
• Every page in docs.json has a file, every .mdx is in the nav, and every internal ](/...) link across all pages resolves
• docs.json parses
• No orphaned screenshots — images/ only holds MCP client icons and the logo
