refactor(BullEye): split into AddressViewer, TransactionViewer, InvoiceViewer

Each widget handles its own concerns: AddressViewer auto-detects network,
TransactionViewer has typed constructors (.bitcoin/.liquid/.ark) with
Ark explorer at explorer.arkade.sh, InvoiceViewer is copy-only.
Renamed localization keys and translated 5 missing languages.
