docs: add self-signed certificate guide

[costajohnt]

Description

Add a new docs page covering how to use self-signed certificates with Seerr. Documents the NODE_EXTRA_CA_CERTS approach with Docker CLI and Docker Compose examples. Updates the four "Use SSL" sections in services.md and mediaserver.mdx to link to the new guide instead of saying certificates are "not supported."

• Fixes Add docs for self-signed certificates #2578

How Has This Been Tested?

• Verified the documentation renders correctly with pnpm start in the docs directory
• Confirmed all internal links resolve to valid pages
• Tested the Docker CLI and Docker Compose examples against the Node.js documentation

Changes

Cohort / File(s)	Summary
New Self-Signed Certificate Guide docs/using-seerr/advanced/self-signed-certificates.mdx	Adds a new page explaining Seerr rejects untrusted upstream SSL connections by default and how to add a CA to Node.js trust using NODE_EXTRA_CA_CERTS. Includes Docker CLI and Docker Compose examples, read-only volume mount guidance, PEM format requirement with an openssl DER→PEM conversion, admonitions, and a link to Node.js docs.
Updated Settings Documentation docs/using-seerr/settings/mediaserver.mdx, docs/using-seerr/settings/services.md	Rewords prior "not supported" language to state self-signed certificates are untrusted by default and can be configured; adds links to the new self-signed certificates guide.

Poem

🐰 I found a PEM beneath the log,
I nudged it, sniffed it through the fog,
Mount it read-only, point NODE right,
Upstream waves in softer light,
Hoppity-hop — all set tonight.
