v0.2.0:1 — drop FOUNDERS50 placeholder from buy-page discount input

Per operator feedback: the discount-code field on /buy/<slug> was
showing 'FOUNDERS50' as a placeholder, which confused buyers (some
tried it as a real code, some assumed Keysat shipped a default
discount). Empty placeholder now; buyers paste their actual code.

No semantic change. Wrapper-only revision; daemon binary unchanged
beyond the embedded HTML template.
