Keep holder preloaded share when retrying decryption

[0xshitcode]

What this changes

Fixes #74 by changing the retry action shown after a decryption mismatch.

Before this change, clicking retry cleared all shares with state.shares = [], which also removed the preloaded holder share from personalization.

Now retry keeps exactly one holder share (identified by isHolder or holder name) and removes the rest, so users can immediately try different friend shares without reloading the holder share.

Also adds an e2e regression test that reproduces the mismatch flow and verifies the holder share remains after retry.

How I tested this

• Added/ran Playwright e2e regression test in e2e/recovery.spec.ts for the decryption-failure retry flow.
• Ran full CI on GitHub Actions runner (make wasm, go test ./..., make lint, make build, make test-e2e) on equivalent branch contents:
