fix(tools): run post_setup in _reconfigure_provider() for env-var providers

_configure_provider() calls _run_post_setup() after collecting env vars
(line 2286). _reconfigure_provider() did not — providers with both
env_vars and post_setup (Browserbase, Browser Use, Firecrawl, Camofox)
skipped the installation step on reconfiguration.

Fix: mirror the _configure_provider() call. post_setup hooks are
idempotent (check before installing), so no behaviour change for users
who already have the dependencies installed.
