Rewrite README with v3.0 roadmap

Polishes the intro wording, removes the Mobile Apps section (the source repo is referenced from invoiceshelf.com instead) and the Credits section, and rebuilds the Roadmap as a single flat checklist that mixes shipped items with in-flight v3.0 work.

Shipped v3.0 items added: decoupled system settings from company settings, proper multi-tenancy system, company member invitations with custom roles, dark mode, full TypeScript refactor of the frontend, improved backend architecture, security hardening.

In-flight v3.0 items (bold + (v3.0) marker so they jump out as the active milestone): reworked installation wizard, Module Directory, rewritten Payments module. The two longer-term items (Stripe integration, improved template system) stay at the bottom unchanged.
