v0.3.0 — Language-independent presence discovery

🌍 Fixes

PSN & Xbox presence discovery now works on non-English Home Assistant instances (#1)

Account discovery previously relied on hardcoded English entity_id suffixes (_online_status, _now_playing). Those suffixes are generated from the translated friendly name by the native integrations, so on a non-English HA instance PSN accounts never appeared in the config flow at all.

• PSN: account selection now uses an entity selector filtered to the playstation_network integration. The account's online-status and now-playing sensors are resolved from the device via translation_key (language-independent) and stored as real entity_ids — never reconstructed from a localized slug.
• Xbox: the now-playing fallback no longer guesses English suffixes; it looks for a media_player on the same device instead.
• Existing (English) configurations keep working without reconfiguration.
• Adds the missing Italian PSN config step and bumps the manifest version (it was still 0.1.0).
