When using KMD wallet for localnet, it's common that the password is set to an empty string. In this case, the memoised logic failed to detect the existing password.

To fix this:
- the password field is initialised to null
- the memoised logic returns the password if it is not null

Add test coverage for KmdWallet's `getPassword` method to verify:
- Empty string passwords are properly cached and reused
- Cancelled prompts (null) fall back to empty string
- Password prompt is only shown once when cached

* feat(*): support customising prompt for KMD password and Mnemonic phrase

There are scenarios where customsing window.prompt are needed:
- window.prompt isn't supported, for example, on macOS WebKit
- a better UI to display the message
To implement this change, I have:
- add options to customise the prompt to KMD and Mnemonic wallets
- when the option isn't set, fallback to the default window.prompt

* prettier

* chore(deps): update dependency vite to v6

* fix(solid): configure Vite for client-side testing

- Disable SSR in `vite-plugin-solid` to ensure client-side environment
- Add development and browser conditions to resolve config for proper
test environment

Two tests that were added upstream in PR #322 instantiate wallets without the
`networks` property, introduced on the current `v4` branch. This change adds
the `networks` property to `MnemonicWallet` and `KmdWallet`, ensuring proper
initialization and tests passing.

* feat(pera): add auto-connect for Pera Discover browser

Add automatic connection attempt when Pera wallet is initialized in the Pera
Discover browser environment. The connection attempt is handled silently with
appropriate logging for success and failure cases.

* fix(pera): add window check to prevent SSR errors

Add type check for window and navigator objects to prevent errors during
server-side rendering. This ensures the Pera auto-connect feature only
runs in browser environments.

* refactor(pera): extract auto-connect logic into private method

Extract auto-connect logic from constructor into a private async method for better
error handling and testability. Update tests to use prototype mocking pattern
consistent with other wallet implementations.

- Move auto-connect logic into private `autoConnect` method
- Use async/await with try/catch for better error handling
- Update tests to mock method on prototype before wallet creation
- Align test patterns with other wallet implementations

* refactor(pera): move Pera auto-connect to resumeSession

Move auto-connect logic from constructor to `resumeSession` method in Pera wallet
implementations to fix SSR compatibility issues. Auto-connect now only triggers
when no other wallet is active and after client-side hydration.

* refactor(pera): remove unused autoConnect method

Remove private `autoConnect` method from Pera wallet implementations since the
functionality is now handled directly in resumeSession.
