style: lowercase all user-facing strings and add custom eslint rule

Comprehensive sweep of all user-facing text to enforce lowercase
convention, including acronyms (api, rest, http, opml, json, totp,
mfa, qr, hmac). Added asa-lowercase/lowercase-strings eslint rule
that reports uppercase in notify() calls, error messages, jsx text,
and checked attributes (placeholder, alt, title).
