refactor(ui): replace direct clipboard copy with CopyWarning component

[luannmoreira]

Description

This pull request refactors all direct clipboard copy functionality in the UI to use the reusable CopyWarning component. Previously, each component implemented its own logic to copy text to the clipboard and show snackbar messages. This change consolidates that behavior into a single, maintainable component, improving consistency across the application.
Obsolete methods such as copyText, copyCommand, and copyMacro were removed where applicable.

Why

• To treat a problem with Permissions API from each browser that prevents using the Clipboard API on non-localhost or unsecure HTTP instances.
• To centralize and standardize clipboard copy behavior.
• To reduce code duplication across components.
• To ensure consistent snackbar messaging on successful copy actions.
• To simplify maintenance and improve future scalability of clipboard-related logic.

Tests

• Updated unit tests for components using CopyWarning.
• Removed tests tied to deprecated methods (e.g., copyCommand()).
• Verified DOM snapshot updates reflect the new component structure.
• Manually tested all updated components to ensure clipboard copying and snackbar messages function as expected.

Perfect changes overall! Just please implement the warning component in ConnectorList.vue and DeviceTable.vue too, since they still have their "native" copying methods with no secure context verification.

Also, since snackbar.showInfo is always called in the components' template, don't you think that it could be called inside CopyWarning, just requiring some copyMessage or copiedItem prop from the components instead of a function?
