Fix the button layout on receive

[n13]

Adds the copy button back - it was flipped vs the design, which made me complain about it to the designer

Review — Verdict: Approve / LGTM

Focused, low-risk UI fix. The core change in receive_screen.dart swaps the bottom-bar content between the two tabs, and this is correct:

• QR tab has no inline copy affordance (just the QR + checksum + address text), so it correctly gets the Copy + Share button row.
• Address tab renders AddressDetailsCard, which already has its own inline per-field copy buttons (address + checkphrase). So the previous Copy button there was redundant; reducing it to a single Share button is right and matches the design.

Other changes

• _copyAccountDetails → _copyAddress now copies just the address (_accountId) instead of the multi-line Account Id … Checkphrase … blob, with the toast updated to "Address copied to clipboard". Consistent with the rename and a cleaner UX — the checkphrase is still reachable via the QR-tab text and the address card's own copy button.
• Removed the now-unused receiveClipboardContent key from app_en.arb / app_id.arb and the generated app_localizations*.dart. Verified there are no remaining references anywhere in the codebase, and both locale files (the only two: en, id) are updated consistently. The hand-edited generated files match what flutter gen-l10n would produce.

Notes / nits (non-blocking)

• The _accountId! force-unwrap in _copyAddress is safe: the bottom content (and thus the Copy button) is only built when !isLoading, which guarantees _accountId != null.
• No unused imports introduced; _checksum is still used by _share, QrCodeTab, and AddressTab.

CI

Analyze check is still pending at review time — worth a green tick before merge, but nothing in the diff looks likely to fail it.

Nice cleanup. 👍
