docs: add KalamDB to known users (#21181)
## Which issue does this PR close?
- N/A. This is a small documentation-only update adding KalamDB to the
Known Users list.
## Rationale for this change
KalamDB uses DataFusion as part of its SQL execution layer. Adding it to
the documentation helps keep the Known Users section accurate and shows
another real-world DataFusion adoption example.
## What changes are included in this PR?
- Added `KalamDB` to the active projects list in
`docs/source/user-guide/introduction.md`.
- Described KalamDB as an SQL-first realtime state database for AI
agents, chat products, and multi-tenant SaaS.
## Are these changes tested?
No code or behavior changed. This PR only updates documentation text, so
no additional tests were needed.
## Are there any user-facing changes?
Yes. The DataFusion user guide will list KalamDB in the Known Users
section.
