fix: SupportPanel form reset + Albedo wallet network compatibility

[jayteemoney]

Summary

Fixes two frontend bugs in the support flow.

#708 — SupportPanel does not clear amount and message after a successful transaction

After a successful payment, the amount and message fields stayed populated, making it easy to accidentally re-send the same support (especially on mobile).

• The success values are snapshotted into submittedAmount / submittedMessage before clearing the live inputs.
• The TransactionResultModal now reads those snapshots, so it still shows the correct amount and note while open — clearing the live fields immediately would otherwise blank out the modal (it renders the props live).
• After a successful submit, the form is cleared.

#707 — Albedo wallet adapter passed the full network passphrase

albedo.tx() expects the shorthand "public" | "testnet", but the full passphrase (e.g. "Test SDF Network ; September 2015") was being passed, so every Albedo sign attempt failed.

• The short network name is now derived from the passphrase via Networks.PUBLIC from @stellar/stellar-sdk.

Testing

• npx tsc --noEmit — no new type errors in the changed files.
• npx next lint on both changed files — no warnings or errors.
• The pre-existing support-panel test pass/fail count is unchanged (failures are environmental and present on main before this change).

Notes

• Changes are minimal and follow existing code style/patterns.
• Freighter and Lobstr adapters are untouched and continue to work.

Closes #707
