fix: Move preset selector from company-profile to SDK dashboard

Presets now shown on the SDK start page (/sdk) as a card grid
between header and stats — only when companyName is empty.
Click navigates to /sdk/company-profile?preset={id}.

Reverted company-profile/page.tsx to original state (no preset
logic there — the dashboard is the right place for discovery).
