feat(tables): migrate /tables page from Jinja2 to Vue 3 + Vite

Rewrite 237-line vanilla JS + Jinja2 template into Vue 3 SFC components
(App.vue, TableCatalog.vue, DataViewer.vue, useTableData composable).
Establishes apiPost POST request pattern for pure Vite pages. Removes
templates/index.html, updates Vite entry to HTML, and Flask route to
send_from_directory. Includes sql_fragments WHERE_CLAUSE escaping fix,
updated integration tests, and OpenSpec artifact archive.
