test: assert the #150 and #151 items the harness did not cover (closes #188)

The suite asserted that the two screens those issues broke now open
without throwing, which is narrower than their definition of done. The
four remaining items are asserted here, additively; nothing existing was
restructured.

Back navigation out of Add Token is checked against the persisted
navigation stack, read from extension storage, as a delta: the round trip
Home -> AddressDetail -> AddToken -> Back -> Back must leave the stack
exactly as it found it. A stale entry is invisible on screen until the
user presses Back one time too many, which is precisely the second-order
damage of #150, so the stack rather than the visible view is what gets
asserted. Stating it as a delta keeps it independent of whatever depth
earlier tests leave behind.

The quick-pick test clicks a button and requires the address field to
hold that button's contract address; the old assertion only counted the
buttons rendered.

The native ETH detail path needed a fixture: the normal-transactions
endpoint answered with an empty list unconditionally, so there was no
non-ERC-20 row to open at all. seedNativeTransfer serves one, and the
detail screen must show the native type, the value, the raw wei quantity
and no token contract row - the row whose branch is where a regression of
the non-ERC-20 case would land.

Tap-to-copy reads the real clipboard back rather than watching the
handler run, after seeding a sentinel so an untouched clipboard cannot
pass. Clipboard permissions are granted context-wide because an
origin-scoped grant is refused for chrome-extension: URLs.

Each of the four was demonstrated failing against a deliberately broken
build; the captured output is in the pull request.
