365c95220 fix(settings): cap PORT at 65535 (#5721)	✅ Yes	Self-host PORT now fails fast at boot if out of the valid TCP range (1–65535), instead of failing later when the HTTP server binds. Documented.

Files changed

• studio/self-hosting/deploy/docker-compose.mdx (en + pt-br): added a tip callout noting PORT must be a valid TCP port (1–65535) and is now validated at boot with a clear error, rather than failing later when the server binds.

Consistency notes

• Checked other self-hosting docs (quickstart.mdx, monitoring.mdx, other deploy/*.mdx) for PORT references — only docker-compose.mdx documents it, no other stale references found.
• quickstart.mdx, concepts.mdx, overview.mdx reviewed — no changes needed for this release's diff.

pt-br translation was auto-generated for the new callout, matching existing translation conventions in the file (technical terms/URLs kept in English).

Summary by cubic

Added a tip to the self-hosting Docker Compose docs (en + pt-br) about PORT validation. PORT must be 1–65535 and is now checked at boot, so invalid values fail fast with a clear error.
