chore: replace mclogs/Minecraft branding strings with iblogs equivalents

example.config.json: legal contact, imprint, privacy URLs swapped to
indifferentketchup.com placeholders; abuse address changed to
samkintop@gmail.com (matches the codex package's author entry);
frontend.name placeholder changed from "mclo.gs" to "iblogs.example".

UI templates: tagline replaced with "Built for game-server logs"
(header.php), meta description rewritten to drop Minecraft & Hytale
framing (start.php), api-docs.php's example "Minecraft version" labels
updated to "Engine version" with a 42.16.3 sample value matching the
codex PZ EngineVersionInformation output shape.

CSS comment "Minecraft Format Colors" tagged as legacy mclogs syntax
palette (the underlying color classes survive untouched — they may
still be useful for highlighting log content).

Footer attribution credit linking back to upstream mclogs and Aternos
is intentionally preserved per the manual-fork rules.

Frontend palette (#5cb85c green accent, etc.) and short-domain choice
remain placeholder values; revisit when iblogs branding is finalised.
