refactor(ohos): StaticMarkdown 604→332 行（Markdown 解析抽到 common/MarkdownParser）

把"文本 → 块/片段"的纯解析逻辑（MdBlock/MdSpan、parseBlocks、parseInline、
表格/分隔线/有序列表判定）整体搬到 common/MarkdownParser.ets（282 行），
StaticMarkdown.ets 只留 StaticMarkdownView 组件（332 行）。

解析规则逐字保留，未改任何排版行为；MdBlock/MdSpan 原本只被
StaticMarkdown.ets 使用（唯一引用方是 components/MarkdownView.ets，
它只用 StaticMarkdownView）。

验证：hvigorw assembleHap BUILD SUCCESSFUL。
