Add npm workspace deduplication utility and CI check

[coderabbitai]

Context

In PR #1994, we identified that duplicated dependency specifications can occur in the webui workspace when multiple node_modules directories exist. Currently, this requires manual intervention to resolve.

Reference: #1994 (comment)

Proposed Solution

1. Add utility task to taskfiles/deps/lock.yaml:

   • Create a task that automates the npm workspace deduplication process
   • Commands to include:

     cd components/webui
     rm -rf node_modules server/node_modules
     npm dedupe
     npm install --workspaces

2. Add CI check:

   • Implement a CI workflow check to detect duplicated dependency specifications
   • This should fail the build if duplicates are found, preventing the issue from reoccurring

Benefits

• Prevents manual intervention for dependency conflicts
• Ensures consistent dependency resolution across the workspace
• Catches duplication issues early in CI before they reach production
