Stabilize SshUrlNoOauthPatFactory SSH key input and editor interactions

[SkorikSergey]

What does this PR do?

Summary

• Paste SSH keys in User Preferences via DriverHelper.type() instead of Actions sendKeys, so private/public key values are entered more reliably.
• Increase short waits while clearing/editing Date.txt in SshUrlNoOauthPatFactory to reduce flaky editor interactions before commit/push.
