Rewrite funding.json to match website voice

Replaces internal/marketing phrasing ("workflow-first", schema/build
jargon) with the user-value framing the website itself uses: "your
calendars are everywhere, KashCal pulls them into one app." Lead
features (iCloud, Quick Add, Insights) and privacy pillars now match
index.html.

Also drops wellKnown from repositoryUrl (must share host with the URL
it qualifies — github.com is not a host we control) and removes the
no-longer-referenced .well-known/funding-manifest-urls + .nojekyll.

Connect any CalDAV server: Nextcloud, Fastmail, Radicale, Baikal, Zoho, mailbox.org, Posteo, Stalwart, SOGo, and more. Subscribe to ICS feeds for holidays, school terms, and sports seasons. See your phone's built-in calendar alongside everything else. Birthdays pull from contacts automatically.\n\nQuick Add turns 'Coffee with Kash tomorrow 3pm' into an event — handling dates, times, recurrence, and locations. Insights show where your time actually goes: busiest days, back-to-back streaks, free blocks, all computed on-device. Home-screen widgets put your day at a glance. Six views (month, agenda, 3-day, week, month-full, year) with pinch-to-zoom and drag-to-reschedule. Available in 67 languages.\n\nPrivate by default: credentials encrypted with Android Keystore, no analytics, no telemetry, no KashCal account. Events stay in a secure database other apps can't read.
