fix(docker): resolve startup failures from broken dependencies and migration runner

• Upgrade telegram-bot-lua to v3.0 from source (v2.0 rockspec broken, pulls v3 code with v2 module map)
• Add luaossl for pgmoon SCRAM-SHA-256 auth
• Remove redundant luarocks (already pulled as transitive deps by telegram-bot-lua v3.0)
• Fix migration runner to handle $$-delimited stored procedures instead of naive semicolon splitting
• Fix missing trailing semicolon on last stored procedure in migration 005
• Fix NULL parameter handling in database.call() for sparse Lua tables (use table.pack + inline escaping)
