The Screen Map had drifted from src/popup/ in both directions. Every entry
was re-verified against the view modules, the view registry in
src/popup/views/helpers.js, the navigation stack in src/popup/index.js and
the markup in src/popup/index.html, and rewritten to match.
Screens added: ExportPrivKey, DeleteWallet, SettingsAddToken.
Flow descriptions corrected: AddWallet is one screen with three tabs, not
an AddWallet screen plus an ImportKey screen reached from a link that does
not exist; ConfirmTx takes an inline password field, not a modal; the
SiteApproval and TxApproval popup mechanisms were swapped relative to
src/background/index.js; a Home transaction row opens TransactionDetail,
not AddressDetail. Back transitions now say "previous screen" with the
actual origins, since every Back button pops the navigation stack.
Also: the xprv wallet type added to the Data Model, the Screen Map and
Supported Functionality; Settings now lists every element it has; the
"Gas estimation and fee display before confirming" TODO checkbox ticked,
as confirmTx.js implements it; and the Clickable Affordance example no
longer cites a UI string that does not exist.
Documentation only. Verified with make check (7 suites, 143 tests, prettier
clean) and with script/cibuild, whose containerized make check ran
uncached.
