feat(auto-redact): move auto-redact to embedPDF

[balazs-szucs]

Description of Changes

This pull request introduces a new "Search & Redact" workflow to the PDF redaction tool, allowing users to search for text across PDFs and redact all matches in bulk. The changes include UI updates, new context API methods, and integration with the underlying PDF annotation and search plugins.

The most important changes are:

Search & Redact Workflow Implementation:

• Added a new SearchAndRedactControls component that provides UI for searching text, configuring options (case sensitivity, whole word), previewing results, and redacting all matches at once. This includes color selection and error handling.
• Updated RedactModeSelector to rename the "Automatic" mode to "Search & Redact" and adjust tooltips and enablement logic to match the new workflow.

Redaction Context and API Extensions:

• Extended RedactionContext and RedactionAPI to include new async methods: searchText and redactText, with support for search options and result summaries. These methods are now available throughout the app.

Integration with PDF Plugins:

• Updated RedactionAPIBridge to implement the new searchText and redactText methods by integrating with the PDF search and annotation plugins. Search results are cached and used to create redaction annotations in bulk.
  UI and Codebase Cleanup:

• Removed legacy controls and advanced settings related to the old "Automatic" redaction workflow from the main Redact tool, and integrated the new SearchAndRedactControls component.

Hi @balazs-szucs Thanks for this its working really well. I did have some issues with the search though. Upon clicking it a second time (without changing the search text) search results all go to 0. Also the search highlight annotations don't clear when I go off the tool having not applied the redaction.

From a UX perspective I feel like I shouldn't have to hit search before hitting redact all matches.

Final tiny niggle, is there a way of the first highlight not being orange? I assume this is because that is the first (active) highlight and it supports you navigating through them. I guess in future we could allow the user to quickly navigate them.

Thanks for the review!

Ah, yeah, I half expected that. For context; It's somewhat of hacky solution. I'll see what I can do particularly about those.
