Pre release fixes v0.8.1

Fixes #2132

And the following reports:

1- When I am creating a robot and copy the token, the token disappears and the robot is not created. It is also possible to edit this field, maybe it should be blocked.

2- Timestamp on notifications are wrong (1/21/1970, 7:12:49 AM, for example) and I eventually needed to refresh the browser to receive the notification.

4- When I choose an order and until the chat opens, it is not possible to see the order id and robot names (these are the first things I ask when someone sends me a message, at least order id visible would be interesting).

5- AUDIT CHAT -> NOSTR: public key is always the same (npub106246s) and your private key is empty (even exporting a file)
AUDIT CHAT -> PGP: your public key, your encrypted private key and your private key passphrase also empty.
The chat works well even one robot using NOSTR and the other API.

6- If you enable Orbot connection, it is not possible to disable even restarting the phone. I needed to reinstall the app.

7- It is not possible to save the keys in a file (NOSTR and PGP) - Error message: Invalid content for clipboard.

8- When the offer list is expanded, the filter buttons are not well aligned, but they can be used.

9- "COPY URL" button is not working when creating an order - Error message: Invalid content for clipboard.

12- When I click on the QR code, it shows the message "Copied!" but only the button "COPY TO CLIPBOARD" works.

13- When the chat is open, the same error that happens on the desktop happens here: AUDIT CHAT without some keys.
