The `wiki_write` tool exposed the Gitea API's `content_base64` parameter directly, requiring callers to provide base64-encoded content. This caused LLM agents to incorrectly infer that other tools like `create_or_update_file` also require base64 encoding, corrupting files with literal base64 strings.
Rename the parameter to `content` (plain text) and handle base64 encoding internally, matching the pattern already used by `create_or_update_file`. Also added test coverage for this.
