Update Russian locale to MiniMessage format with full key coverage

[Copilot]

The Russian locale (ru.yml) was outdated — using legacy &-style color codes, missing a significant number of keys added in recent versions, and containing grammatical errors.

Changes

• MiniMessage migration: Replaced all &c/&a/&6 etc. color codes with MiniMessage tags (<red>, <green>, <gold>, <dark_green>, etc.)
• Added missing keys:
  • warps.error.not-correct-rank
  • Full warps.gui.* section (titles, buttons, tips)
  • warps.conversations.prefix
  • togglewarp.* (enable/disable warp command messages and errors)
  • protection.flags.PLACE_WARP.*
• Removed stale keys: Dropped legacy warps.next, warps.previous, warps.title, warps.random (superseded by warps.gui.*)
• Bug fix: protection.flags.PLACE_WARP.description was "Предотвращает размещение варпа" (Prevents placing a warp) — corrected to "Разрешает размещение варпа" (Allows placing a warp) to match the English meaning
• Terminology: Standardised on "варп" throughout, replacing inconsistent "знак телепортации" / "знак деформации" usages

Example of the formatting change:

# Before (legacy)
warps:
  deactivate: "&cСтарый знак телепортации деактивирован!"
  error:
    no-permission: "&cУ вас нет разрешения на это!"

# After (MiniMessage)
warps:
  deactivate: <red>Старый варп деактивирован!</red>
  error:
    no-permission: <red>У вас нет разрешения на это!</red>

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
