fix(i18n): migrate Ai.qml and fix OSD.qml i18n calls

OSD.qml: fix i18n.t() -> I18n.t() (lowercase caused empty strings)

Ai.qml: migrate hardcoded user-visible strings to I18n.t():
- /model command: model not found, switched to model messages
- /help command: full help message
- API key missing error (with model name and key_id substitution)
- Network request failed error
- No response from API message
- Command executed successfully (no output) message
- Model descriptions for all 6 providers

translations: add 13 new keys to en/ru/es (ai.api_key_missing,
ai.cmd_no_output, ai.desc_*, ai.env_variable, ai.help_message,
ai.model_not_found, ai.network_failed, ai.no_response,
ai.switched_to_model)
