fix: address numerous long-standing console errors (python & web)

[mistercrunch]

Summary

• fixing console errors related to aggrid/i18n seems those i18n files were not tied to anything ... see analysis below
• tackled various annoying console issues in python
• tackled some browser console warning

analysis

Import Chain Analysis:

1. i18n.ts → imported by consts.ts (line 21)
2. consts.ts → calls addLocaleData(i18n) (line 23) and exports constants
3. consts.ts → imported by controlPanel.tsx, AgGridTable/index.tsx, and utils/getAggFunc.ts

Key Finding:

The translation strings in i18n.ts don't appear to be used anywhere. The grep search shows:

• Control panel strings like "Query Mode", "Aggregate", "Raw Records" exist in code but use enum values
  (QueryMode.Aggregate) rather than translated strings
• Pagination strings like "page_size.show", "table.previous_page" are only found in the i18n.ts file itself - not
  referenced elsewhere

Registration vs Usage:

• Registration: The i18n data gets registered via addLocaleData() when consts.ts is imported
• Usage: The actual translation keys aren't referenced anywhere in the codebase using t() calls

Conclusion:

The i18n.ts file contains translation keys that were likely intended for the ag-grid table plugin but are not
actually used by any components. The addLocaleData() call registers translations that are never looked up, making
this essentially dead code.
