feat(app): replace the launcher icon with a HardenedPass one

The launcher still showed Password Store's icon. The new one is a shield
shaped lock with a git branch cut through it, steel with an ember
shackle on a dark tile. The cut is transparent, so the foreground also
works without a tile on the welcome screen and in the autofill picker.
The monochrome layer is the same figure.

Debug builds now override only the background, in violet, and share the
foreground. The density PNGs go: minSdk 26 always uses the adaptive
icon. The Play Store PNGs were unused. Two lint baseline entries for
those PNGs go with them.

The old Play Store banner, referenced nowhere, becomes media/banner.png
with the new icon and name, and heads the README.
