Fix TS2300 duplicate import errors in HoverButtons.tsx blocking CI build

[Copilot]

PR #101 introduced a merge conflict resolution that left duplicate import { Configuration, CustomizedGridType, DataGridPlot } statements in HoverButtons.tsx, causing 6 TS2300: Duplicate identifier TypeScript errors and failing the build-and-packaging CI job.

Root cause

When develop (which had consolidated those three identifiers into a multi-line block also containing PlotType) was merged into the PR branch, both the original single-line import from the PR and the expanded block from develop ended up coexisting:

// Conflict residue — two imports declaring the same identifiers
import { Configuration, CustomizedGridType, DataGridPlot } from '../../types';  // PR line
import {
  Configuration,       // duplicate
  CustomizedGridType,  // duplicate
  DataGridPlot,        // duplicate
  PlotType,
} from '../../types';

Changes

Bug fix

• HoverButtons.tsx — Removed the redundant single-line import; retains only the multi-line block (which already covers all needed identifiers including PlotType). Updates @mantine/hooks import to add useElementSize and useMergedRef, replaces hoverRef.current.offsetWidth with reactive containerWidth from useElementSize.

Feature changes from PR #101 (applied cleanly)

• CustomizeSmoothing.tsx (new) — UI for Gaussian and Savitzky-Golay filter parameters with apply/restore workflow per selected plot
• CustomizeUnaryOperations.tsx (new) — UI for composing ordered scalar operations (add/subtract/multiply/etc.) per selected plot
• utils/fetchData.ts — Adds getSmoothingMethods, getOperationMethods, buildSmoothingRequest, formatOperations, and smoothing/operations query-string encoding in fetchDataPlot
• utils/plot.ts — Adds reapplyAxisOrder to restore user axis transposition after back-end re-fetches; passes smoothing and operations through plotNodeUriLoaded
• types/plot.ts — New SmoothingParams and UnaryOperation types; smoothing and operations fields on BaseDataPlotly
• types/data.ts — Extended DataManipulationParameterResponse with fields, group_label, optional possible_values; DataManipulationMethodResponse with additional_parameters
• DataplotCustomization.tsx — Registers new Data smoothing and Unary operations accordion panels
• CustomizeDownsampling.tsx / CustomizeInterpolation.tsx — Call reapplyAxisOrder after re-fetch to preserve transposition
• MainLayout.tsx — Preserves smoothing and operations fields when rebuilding plot objects on config load
