Add Capsuleers.app to community tools

[WilliamFalci]

Adds docs/community/capsuleers-app/ — a bilingual (EN/IT) community site and gameplay toolbox: news and player-written articles, public character/corporation/alliance profiles, a killboard over a 90-day killmail archive, a live regional map and a sovereignty map with a campaign layer, plus fitting, industry planning, asset, jump, route, fleet and battle-report tools, and three OBS streaming overlays.

Listed as a service: it is hosted and used directly by players, nothing to install.

Character data goes through EVE SSO and ESI. OAuth tokens are never sent to the client — every authenticated call is made by a server-side proxy that verifies the character belongs to the session and carries the required scope.

Two things worth stating up front rather than leaving to be discovered:

• The fitting engine behind the fitting tool is open source and published separately on npm as eve-fit-engine (submitted separately, Add eve-fit-engine to community resources #316).
• Ship hulls are rendered with ccpwgl2, the community WebGL implementation of the game's own renderer, which means the 3D viewer reads the client's own resources rather than showing a static image. The page says so plainly. If that is something the docs maintainers would rather the page described differently, or not at all, say the word and I will change it.

Against the listing requirements:

1. EVE related — the whole site is EVE Online.
2. Developer License — free, no charge for access, no sale of anything; the in-game ISK donation overlay reads a streamer's own wallet journal and is not a monetisation channel. The full intellectual property and non-endorsement notice is on the Terms of Service page and a copyright line is in the footer of every page.
3. Public — https://capsuleers.app, no account needed for the public surfaces.
4. Production ready — three replicas behind a public status page, in daily use.
5. Public for at least three months — publicly reachable since 2026-05, opened to indexing on 2026-05-16.
6. Actively maintained — released continuously, most recently this week.
