fix: Guac UI dark theme, working End Session button, and themed overlay#3020
Conversation
- wait.html / error.html / index.html: Apply CAPE Bootstrap dark theme (bg-dark, navbar header, Bootstrap components) to match the rest of the UI. Previously these pages used bare unstyled HTML. - index.html toolbar: Thin bg-dark bar with CAPE logo, task link, and End Session button; Guacamole canvas fills remaining viewport height. - guac-main.js stopTask(): Add X-CSRFToken header so the POST succeeds under Django CSRF protection. Redirect to task status page on success. Show spinner on button while request is in flight. - guac-main.js disconnect overlay: When the Guacamole connection drops, show the #launch_error overlay via CSS display:block instead of the jQuery UI .dialog() widget (which was never loaded). Normal session end shows green "Session Complete"; unexpected disconnect shows red "Session Error". - guac-main.css: Dark overlay styling for the disconnect dialog using CAPE colors (#212529 bg, white text). - apiv2/views.py tasks_status: Enable user_stop (was disabled) so End Session POST actually signals the guest VM to complete.

Code Review
This pull request focuses on UI improvements for the Guacamole console, including a new toolbar, updated error and wait pages using Bootstrap, and a dark theme. It also updates the tasks_status API to support both session and API key authentication and improves the stopTask JavaScript function with CSRF protection and better user feedback. Feedback was provided regarding the significant removal of the yara_uploader functionality and the use of hardcoded inline styles in the Guacamole index template that duplicate existing CSS classes.

The yara_uploader function and its associated logic (including imports for yara, plyara, and sqlalchemy.select, as well as the ALLOWED_YARA_CATEGORIES constant) have been entirely removed in this PR. This appears to be a significant deletion of functionality that is not mentioned in the pull request title or description. If this was unintentional (e.g., due to an incorrect rebase or accidental deletion), please restore the code. If it was intentional, it should be explicitly documented as it represents a breaking change to the API.

The error dialog overlay uses hardcoded inline styles that largely duplicate the .dialog and .inner classes defined in web/static/css/guac-main.css. Using the CSS classes instead of inline styles improves maintainability and ensures consistency across the UI. Note that the colors in the inline styles (e.g., #212529) also differ slightly from the ones defined in the CSS file (#1e1e2e).

Summary
The Guacamole pages (wait, session, error) used bare unstyled HTML while the rest of CAPE uses Bootstrap dark theme. This PR applies the CAPE dark theme consistently and fixes the End Session button which was silently failing.
