[feature] - More Configuration

[glitch-txs]

What problem does this new feature solve?

Describe the solution you'd like

• Allow to hide "All Wallets" button (only on desktop).
• Tokens config to allow override native cryptocurrency images. Solves [bug] Custom chains do not expose a way to set a custom token image for the native gas token #1406
• Custom chain images must be shown in all views (when the user is connected and switches to that chain) - not only on the Networks View. Solves [bug] Custom chain images do not propagate to the current chain button when opening the modal #1405

Could you expand on last 2 points please

I'll reopen an issue with the first item alone, as we have already other opened issues for the rest of features.
