feat(bitable): U2 inline field configuration in column header menu

- Add InlineFieldConfigurator.vue (inline panel reusing FieldConfigForm logic)
- Add fieldRenderUtils.ts (type conversion compatibility check)
- Refactor ColumnHeaderMenu: edit -> inline expand, batch -> open FieldManagePanel
- Integrate InlineFieldConfigurator in BitableGrid header slot
- Add batch-management banner to FieldManagePanel
- Add submitting loading state to prevent duplicate clicks
- Extend e2e/bitable-field-ops.spec.ts with inline edit scenarios

Closes R1 (P0): column header menu inline edit, no more drawer jump.

+ *
+ * `checkTypeCompatibility` implements the conversion matrix from the U2 spec:
+ *   - text <-> select/multiselect: compatible (values double as options)
+ *   - number -> text: compatible
+ *   - text -> number: compatible only if every non-empty value parses as a number
+ *   - date -> text: compatible (ISO string)
+ *   - text -> date: compatible only if every non-empty value is ISO-date-shaped
+ *   - attachment/image/formula/lookup -> anything: NOT compatible (structured data)
+ *   - anything -> attachment/image/formula/lookup: NOT compatible (can't synthesize)
+ *   - select <-> multiselect: compatible (shared option list, single value <-> [single])
+ *
+ * ponytail: unlisted pairs are blocked conservatively. Ceiling: a few safe pairs
+ * (e.g. number -> select) are also blocked to keep the matrix small and explicit;
+ * upgrade path = extend COMPATIBLE_PAIRS / add a guard below with a test.
