[Feat]: Ambiguous behavior when attempting to connect with a Solana dapp with all Sol accounts hidden

### Describe the bug

Expected behavior is a bit unclear for the scenario where a user has hidden all their Solana accounts but attempts to connect with a Solana dapp.

### Expected behavior

TBD

We might expect the user to have to explicitly unhide a Solana account before it can be selected and shared with the requesting dapp.

### Screenshots/Recordings

### Steps to reproduce

1. Hide all Solana accounts
2. attempt to connect with a Solana dapp

Current behavior:
- See that one of the hidden Solana accounts is picked as default
- When choosing to edit accounts during dapp connection, see that the Solana accounts become unhidden

### Detection stage

During release testing

### Version

12.18.0

### Build type

Other (please specify exactly where you obtained this build in "Additional Context" section)

### Browser

Chrome

### Operating system

MacOS

### Hardware wallet

_No response_

### Additional context

Produced in the latest RC build
release-candidate build from git id: 7eb90e00

### Severity

low severity because most users will not hide all their Solana accounts. It's more of a question of the intended UX for this scenario.

Start with the listed reproduction steps in Chrome on macOS using the release-candidate build, hiding all Solana accounts before connecting to a Solana dapp. Review the attached recording and clarify the intended UX with maintainers; done means the all-hidden-account behavior is agreed and verified, including account selection and visibility changes.
