[Bug]: Connect button invisible on instance card (Tailwind cascade order bug with group-hover:opacity-100 vs opacity-0)

[RodrigoAraujo2]

Prerequisites

• I have searched existing issues to ensure this bug hasn't been reported before
• I have read the documentation
• I am using a supported version of Evolution Manager

Bug Description

On the Instances list page (/manager/instances), the action buttons on each instance card (Connect, Settings gear, Delete) are invisible even on hover, although they exist correctly in the DOM and are fully functional (clickable via keyboard focus / programmatic click).

Root cause found via DevTools: the button wrapper has both opacity-0 and group-hover:opacity-100 Tailwind classes. The compiled CSS rule .group-hover\:opacity-100:is(:where(.group):hover *) { opacity: 1; } exists correctly in the stylesheet and the .group ancestor (the card) DOES receive :hover correctly when the mouse is over it (verified with element.matches(':hover') = true), but the computed opacity of the wrapper stays at 0 regardless. This points to a CSS cascade/specificity ordering issue in the compiled Tailwind output (likely the opacity-0 utility rule being emitted after the group-hover:opacity-100 rule in the same layer, so it wins the cascade despite both having equal specificity).

Workaround confirmed: injecting .group:hover .group-hover\:opacity-100 { opacity: 1 !important; } via a custom stylesheet fixes it immediately.

Steps to Reproduce

1. Deploy Evolution Go + Manager via Docker (image: evoapicloud/evolution-go:latest)
2. 2. Log in to the manager and go to /manager/instances
3. 3. Create an instance
4. 4. Hover the mouse over the instance card, over the area below the "Status" row (where the Connect/Settings/Delete buttons should be)
5. 5. Nothing appears; the card looks empty below the Status row

Expected Behavior

Hovering over the instance card should reveal the Connect / Settings / Delete action buttons (they are visually hidden by default via opacity-0 and meant to be revealed via group-hover:opacity-100, but the reveal never happens).

Actual Behavior

No buttons are visible on hover. Inspecting the wrapper element shows computed opacity: 0, even while the .group ancestor genuinely matches :hover (confirmed via JS: group.matches(':hover') === true). The buttons still exist in the DOM and are fully clickable (via keyboard Tab+Enter or programmatic click), so this is a pure CSS rendering bug, not a logic/JS bug.
