Add market share to CX overview table

[richjenks]

Added market share percentages to the CX overview table in these places:

1. Plan: using daily delta
2. Empire: using daily delta
3. ROI Overview: outputs × buildings × runs × 1.25*

• COGC with 0 experts

Also fixed small annoyances I came across along the way:

• Improved CX tooltip positioning, considering surrounding UI, horizontally (e.g. Plan) or vertically (e.g. Construction Cart) as appropriate. General text tooltips unchanged.
• Hover any part of MaterialTile to show CX overview table, not just ticker text
• Fixed broken HTML entities in translation files for Empire screen

False positive from codacy imo, I don't think this should prevent merging.

cx is the app's known exchangeTypesArray used to read from the app's known overviewData. No user input or opportunity for malicious manipulation.

Similar pattern already exists in a dozen places so making codacy happy is a fair bit of work with no apparent benefit (e.g. line 197 that predates this PR, useExchangeData.ts, planningStore.ts, usePlanetData.ts)
