fix: share payment targets dialog with reactions row, restore QR glyph

- Extract PaymentTargetsDialog from PaymentButton so the reactions row
  can render the same QR/Copy/Pay layout instead of the legacy two-row
  M3ActionRow per target.
- PayReaction now subscribes via EventFinderFilterAssemblerSubscription
  and observes the PaymentTargetsEvent reactively, so targets actually
  load when the wallet icon is tapped.
- Correct the QrCode2 codepoint (U+E00A) and re-subset the bundled
  Material Symbols Outlined font so the glyph is no longer a tofu box.
