NeedmeFordev 1a1b5aa53e Fix: respect the internet toggle before running Tavily web search (#14051) (#14052) ...

### What problem does this PR solve?

Fixes #14051.

The chat UI already sends an `internet` flag with each request, but the
backend previously triggered Tavily web retrieval whenever
`prompt_config.tavily_api_key` was configured. As a result, web search
could still run even when the internet toggle was off.

This PR makes web search an explicit opt-in at request time:
- `tavily_api_key` only indicates that web search is available
- Tavily retrieval runs only when `internet` is explicitly enabled
- the same behavior now applies to both the normal retrieval path and
the deep-research / reasoning path

This also fixes the no-KB fallback case so chats without KBs fall back
to normal solo chat when `internet` is off.
