Faction tooltip text and Resistance icon rendering are inconsistent in charts

[Francespo]

Objective

Make faction presentation consistent in main charts by showing the correct information in tooltip and legend.

Context & Symptoms

• In Faction Performance, hovering chart bars shows the faction symbol instead of the faction name.
• In Game Distribution, the legend does not show the Resistance faction symbol.
• In other places where Resistance appears (for example with T-70 X-wing as top ship), the faction name appears but the colored faction symbol is missing.

Expected Outcome

• In Faction Performance, the tooltip always shows the full faction name.
• In Game Distribution and related views, the Resistance symbol is rendered correctly with the expected color.
• The legend behavior remains unchanged where it is already correct.

Technical Implementation Plan

Scope

• Make faction presentation consistent in charts where issue symptoms were reported.
• Ensure Faction Performance tooltip shows full faction names.
• Ensure Resistance icon rendering is consistent in Game Distribution and related faction displays.

Non-goals

• No changes to analytics API contracts or data model.
• No changes to chart metrics/business logic.
• No redesign outside the impacted chart presentation layer.

Proposed Approach

1. Update Faction Performance chart labeling/tooltip configuration so tooltip titles use readable faction names.
2. Verify and correct faction icon class mapping and key normalization for Resistance rendering.
3. Align faction display mapping usage across affected chart/legend UI blocks to avoid inconsistent outputs.
4. Add a safe visual fallback so label + color remain clear even if icon glyph rendering fails in a specific context.

Test and Validation Strategy

• Hover each faction bar and verify tooltip title uses full faction name.
• Verify Game Distribution legend shows Resistance with expected icon behavior and color.
• Spot-check related UI sections that render faction icon + label combinations.
• Run frontend static validation/check after changes.

Risks and Rollback

• Risk: small visual inconsistencies in other faction renderers that share icon mapping.
• Rollback: restore previous tooltip config and icon mapping logic in the dashboard view.
