revert: temporarily restore content to the last Play-Store-compatible state

The live Play Store release (wallet-android 85bde7e, published 2026-06-15)
was built against whatever was on this branch's HEAD at the time - which,
since master had received no commits between 2026-03-02 and this week, was
commit 7a087cf. This week's changes (nova-base sync, Tron config/icons,
balance test fixtures, etc.) are real and wanted, but they've made master
incompatible with that still-live app version, and live users installing
fresh right now get a completely empty tokens list because of it (the app's
chain sync silently fails whole-hog on any single malformed/incompatible
chain entry, leaving new installs with zero locally-cached chains).

This makes master's served content match 7a087cf exactly, stopping the
bleeding for current live users without needing an emergency app release.
None of this week's work is lost - it's all preserved on
pending/post-fix-release and will come back once wallet-android's Tron
send feature is complete and both repos can ship together in one
coordinated release.
