docs: surface Nous Portal on pages where it solves a real problem the page describes (#30874)

Follow-up to #30869. Adds Portal mentions on user-facing pages that
naturally call for an LLM + tool credentials but didn't previously
acknowledge Portal as a one-stop option.

- getting-started/installation.md: tip after the 'after install' block
  pointing at 'hermes setup --portal' for users who want everything wired
  at once instead of piecewise via 'hermes model' + 'hermes tools'.
- user-guide/configuring-models.md: small tip near the top — the page is
  literally about provider/model choice and previously had zero Portal
  mention.
- user-guide/features/voice-mode.md: Prerequisites need both an LLM and
  TTS — a Portal subscription is the single setup that covers both.
- user-guide/features/batch-processing.md: highlights Portal as a
  predictable-cost option for parallel agent runs that hit many APIs.
- user-guide/features/api-server.md: backend needs models + tools; one
  Portal sub gives a fully-equipped OpenAI-compatible endpoint.
- user-guide/windows-native.md: early-beta users on Windows benefit most
  from skipping per-tool Windows-key-juggling.
- integrations/providers.md: updates the existing Tool Gateway tip and
  the Nous Portal section to mention the new commands.
- user-guide/features/fallback-providers.md: Nous row in the provider
  table now lists 'hermes setup --portal' as the fresh-install path.

Tone discipline: one Portal mention per page, concrete CLI commands
(no marketing copy), always solving a problem the page itself sets up.
