Bring back the official webview

[BrightDV]

• [x] retrieve antibot cookie
• [x] retrieve login cookie
• [x] webviews flow (antibot/cookie/session)
• [x] add a switch in the settings to choose which webview to use (to prevent it from being unusable too long)
• [x] fix expired date of antibot cookie
• [x] replace the current implementation of the webview, partially: needs to prevent temp screen being shown

Needs further testing to the complete flow.
