UI: Create Mirror And Mirror Overview Improvements

[Amogh-Bharadwaj]

UI Improvement Features

These are some features which I thought would be nice to get in. At the end of the day, these are just proposals from my end.

Mirror Create Pages: Error Toasts And Floating Button

We now show errors as toasts and have the Create Mirror button with a fixed position on the bottom-right. Users now don't have to do a lot of scrolling up and down to look at the error message, come back, and click create.

QRep Mirror: Upsert Columns

Selection of Unique Key Columns for QRep Upsert mode now looks like this, saving users from having to type out columns. Also added validation for the columns being an empty array.

Better Tabs UI for Mirror Overview

I thought the tabs we have there look unpolished so used Tremor to come up with this. This also achieves significant code reduction in that file.

Wiring Status in Mirror Overview Page

Wires in the Status we show in the mirror overview page. This is a follow-up to #883

Others

• Removes 'Authentication failed' message in login landing page.
• Makes the source-destination table list in Mirror Overview page have scrollable height and sticky headers
• Error table now has time column before message column and the rows are sorted by timestamp (latest first)
