ui: replace Bitcoin/Electrum branding with Bitcoin Purple/Electrum Purple in dialogs

Replace all user-visible "Bitcoin" and "Electrum" strings across Qt and QML
GUIs with "Bitcoin Purple" and "Electrum Purple" respectively. Update the
Help menu: replace the Bitcoin Paper link with the Bitcoin Purple whitepaper
and point the official website to bitcoinpurpleblockchain.com. Remove the
"Distributed by Electrum Technologies GmbH" attribution from the About dialog.
No code identifiers, class names or technical references were modified.
