Add visible linting error when queries entered in Fleet UI use alias strings containing dots prior to query run

[nonpunctual]

This bug report https://github.com/fleetdm/fleet/issues/18694 was rejected because it was decided that documentation of this issue was sufficient. It isn't.

Currently, entering a query with dots in alias names must be run to inform a user that their query will fail.

Problem

Please see: https://github.com/fleetdm/fleet/issues/18694 for context.

Potential solutions

1. Please add a visible error when the SQL query linter in Fleet UI discovers dots in alias labels
2. Please fix the issue handling dots in alias names in the UI
