chore(deps): pin typer<0.26 to keep external click for CLI

typer 0.26 vendors its own click as `typer._click` and drops the external click
dependency. roboflow/cli/_compat.py subclasses TyperGroup using external click
types, so under typer 0.26 the CLI mistypes (mypy fails) and click isn't
installed at all. typer 0.25.x still depends on external click and type-checks
(it's what main resolved to on 2026-05-25). Pin typer<0.26 and declare click
explicitly so `make check_code_quality` passes and the CLI keeps working.
