Description and Related Issue(s)

Resolves #3163

This PR adds support for displaying attribution information in public tag tooltips. The attribution can include a source name with an optional icon and link, helping users understand where the tag information comes from when provided by public tag providers.

Proposed Changes

• Added support for tooltipAttribution and tooltipAttributionIcon fields in address metadata parsing
• Updated EntityTagTooltip component to display attribution in a "Source:" section at the bottom of the tooltip
• Attribution can be displayed as plain text or as a clickable link (when a URL is provided)
• Attribution icon is displayed when tooltipAttributionIcon is provided
• Updated TypeScript types to include the new metadata fields
• Added visual tests for the tooltip with attribution in both light and dark modes

Breaking or Incompatible Changes

None. This is a backward-compatible addition that only enhances the tooltip when attribution metadata is provided.

Additional Information

The attribution section appears at the bottom of the tooltip, separated by a divider when other tooltip content is present. The attribution supports both plain text and URL formats, with automatic link formatting when a URL is detected.
