feat: add private key viewing for addresses

Add a 'Show private key' button on the address detail view that opens
a dedicated password-prompt screen with a clear warning about key
sensitivity. After correct password entry, the derived private key is
displayed in a read-only well with a copy button.

- Add getPrivateKeyForAddress() to wallet.js
- Add showPrivateKey view with password verification
- Add clipboard policy section to README explaining why we never
  auto-clear the clipboard
- Register new view in helpers.js VIEWS array and wire up in index.js

+#### Clipboard Policy
+
+AutistMask never clears or overwrites the user's clipboard. When sensitive data
+such as a private key is copied, it is the user's responsibility to manage their
+clipboard afterwards. We deliberately avoid auto-clearing the clipboard for two
+reasons:
+
+1. **User expectations**: silently modifying the clipboard violates the
+   principle of least surprise. The user initiated the copy and knows the
+   content is sensitive.
+2. **Data safety**: the user may have copied something else important in the
+   intervening time. A timed clipboard clear would destroy that unrelated data.
+
+The warning shown before revealing a private key makes it clear that the key is
+sensitive and that clipboard management is the user's responsibility.
