fix(pro): single-source the platform Lightning address + show it to payers

The pay-to address was duplicated (PRO_LIGHTNING_ADDRESS and
PLATFORM_LIGHTNING_ADDRESS) and hardcoded in the tour zap-split; a typo in any
copy would send money nowhere. Now one source of truth in src/lib/platform.ts,
re-exported by the fee/Pro modules.

Also surface the address in the Sasquatch Pro dialog ('Pays to ⚡ <address>') so
users can see where their sats go, in both the auto-pay and manual-QR paths.
