Update and polish Russian localization

[purpurcof]

This pull request updates and refines the Russian localization file (ru.yml) to align it with the current English template (en.yml).

Key changes:

• Added missing keys: Brought in keys that were present in en.yml but missing in ru.yml (e.g., CPU_CORES, DONATION_KEY_REQUIRED, new purge parameters, network tests, RAM statistics, etc.).
• Corrected grammatical agreements: Fixed gender and pluralization agreements inside brackets {} to match Russian grammar rules (e.g., adjusted the consumer queue status variables to proper feminine agreements).
• Improved in-game phrasing: Replaced literal translations with more contextually accurate terms (e.g., in DIRT_BLOCK, the literal translation for "dirt block" was updated to "safety block" to match the actual English context).
• Resolved placeholder ordering: Adjusted the phrasing in complex messages (such as PATCH_SKIP_UPDATE and PREVIEW_TRANSACTION) to preserve the exact variable/placeholder sequence, avoiding potential parsing or rendering issues.
• Typography adjustments: Standardized the use of Cyrillic quotes (« ») inside values and removed duplicate periods at the end of inspector tooltips.
