Shipping Labels: Add new screen to select category for HAZMAT

[itsmeichigo]

Closes: #15314
Also closes #15243

Description

This PR adds a new screen for selecting categories for HAZMAT. A few notes:

• We have a list of HAZMAT categories in the legacy flow, but I found some items no longer listed on the Woo Shipping plugin (on the web). So I filtered those out of the list to match with the web.
• The search bar added using searchable has some problems with the layout and text color (as reported in Blaze: Location search bar doesn't show placeholder initially #15243). I found that this was caused by our workaround of applying appearances to all the search bar in the app. This is not a good solution for the customization, and the search bars look better without it so I removed the legacy code. Please let me know if you think this should be reverted.

Steps to reproduce

• Log in to a test store with Woo Shipping set up.
• Open a completed order with at least one physical product.
• Select create shipping label > HAZMAT > enable the toggle and tap Select category.
• Confirm that the Select Categories screen matches the design, and filtering using search bar works correctly.
• (Optional) Confirm that the category list matches the list on the web.
• (Optional) Confirm that the search bars on other screens (order/product/coupon/product category search/Blaze) still look nice.

Testing information

Tested on simulator iPhone 16 Pro iOS 18.2 and confirmed that the new screen matches the design. The search bar looks good on all screens.

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
