[Ecosystem > TMA] Create pages for launch parameters & init data explanation in TMA section #1981
Description
rn docs have no pages explaining what data Telegram passes to a Mini App or how to authenticate users.
This should be added:
- New "Launch parameters" page: what Telegram passes at startup, parameter reference table, start parameter for deep linking
- New "Init data" page: what init data is, how to send it to the server, validation, field reference
Follow-up: Next PRs will cover UI components, dev workflow, and SDK overview.
