docs: remove nonexistent TALOS_ prefix from Talos config env vars

[jonas-jonas]

The Talos server only reads unprefixed config env vars (e.g. SECRETS_HMAC_CURRENT), so the documented TALOS_-prefixed forms are silently ignored and the published docker instructions fail. Removes the prefix from the config reference, CLI pages, and all operate guides; see ory-corp/cloud#13016.

Summary by CodeRabbit

• Documentation
  • Updated configuration guidance to describe environment-variable overrides without requiring a legacy prefix.
  • Revised database, security, tracing, logging, and Docker examples to use the current environment-variable names.
  • Updated CLI reference documentation to clarify how environment variables and schema defaults apply when no configuration file is provided.
  • Improved consistency across operational guides and command-line help.

📝 Walkthrough

Walkthrough

Talos operational and CLI documentation was updated to replace TALOS_-prefixed environment-variable examples and descriptions with unprefixed variables and generalized environment-variable behavior.

Changes

Talos environment variable documentation

Layer / File(s)	Summary
Operational configuration examples docs/talos/operate/...	Configuration, database, Docker, tracing, secrets, security, and troubleshooting examples now use unprefixed environment-variable names.
JWK and keys CLI help text docs/talos/reference/cli/talos-jwk-*.md, docs/talos/reference/cli/talos-keys-*.md	CLI descriptions now state that schema defaults and environment variables apply when --config is omitted.
Migration, proxy, and serve CLI help text docs/talos/reference/cli/talos-migrate*.md, docs/talos/reference/cli/talos-proxy.md, docs/talos/reference/cli/talos-serve*.md, docs/talos/reference/cli/talos.md	Inherited --config descriptions no longer restrict environment variables to the TALOS_ prefix.

Pull request overview

This PR fixes Ory Talos documentation so configuration via environment variables matches actual server behavior (unprefixed env vars), preventing broken Docker/ops setups caused by silently ignored TALOS_-prefixed variables.

Changes:

• Updates the Talos configuration reference to document unprefixed env vars (for all config keys, including required vars).
• Updates all Talos CLI reference pages to remove wording that implies TALOS_-prefixed env vars.
• Updates Talos operate guides (deploy, database, troubleshooting, secrets, tracing, configuration) to use unprefixed env var examples.
