[MINOR] fix: polish log and error message quality in core, server, and trino-connector

[markhoerth]

This PR improves the English quality of user-facing log messages, exception
messages, and configuration descriptions across core, server, server-common,
trino-connector, and audit modules. All changes are native English speaker
corrections — no logic or functional behavior changes of any kind.

Changes applied consistently:

• "Can not" / "can not" → "Cannot"
• "Fail to" → "Failed to"
• "id" → "ID" when used as an identifier abbreviation
• "SIP" → "SPI" (typo in GravitinoConnectorPluginManager)
• "Grivitino" → "Gravitino" (typo in GravitinoConfig)
• Removed trailing periods from log and exception messages
• Fixed missing spaces after colons in log messages
• Fixed non-idiomatic phrasing ("would better use", "throw a exception", "occurs an unexpected")
• Improved GravitinoConfig property descriptions for clarity
• Removed a placeholder dev comment left in production code

A follow-on PR will cover the catalogs modules.

@jerryshao FYI — first PR contribution, happy to adjust anything that doesn't fit the project's conventions. A follow-on PR for the catalogs modules is planned.

You can use ./gradlew spotlessApply to fix all possible formating problem before pushing code.
