Localazy rebrands translation tiers, adds human AI review services

The 'Translation Services' section was renamed to 'Human translation services' and its description rewritten: removed 'proofreading' from service list, added 'human review of AI-translated strings', changed intro from 'Let our professional translators translate your project' to 'Get human translation services directly on the platform', and removed 'selected services' from the price dependency sentence.

The 'MT & AI-powered features' section was renamed to 'AI-powered features & machine translation' and its description rewritten: removed mention of credits renewing monthly and upcoming AI-powered workflows; now emphasizes day-to-day MT needs and Localazy AI.
