feat(web): refine system model settings to 4 distinct config states

Replace the single `defaultModelNotConfigured` boolean with a derived
`systemModelConfigStatus` that distinguishes between no-provider,
none-configured, partially-configured, and fully-configured states,
each showing a context-appropriate warning message. Also updates the
button label from "System Model Settings" to "Default Model Settings"
and migrates remixicon imports to Tailwind CSS icon classes.
