fix: handle MAL API returning numbers instead of strings for zero-value statistics

The MyAnimeList API inconsistently returns statistics status fields (watching,
completed, on_hold, dropped, plan_to_watch) as quoted strings for non-zero
values (e.g. "8217") but as bare numbers for zero values (e.g. 0). This caused
JSON unmarshal errors for anime with zero counts in any status field.

Introduce a FlexString custom type that implements json.Unmarshaler to accept
both JSON strings and JSON numbers, always storing the result as a string. The
type definition lives in MALTypes.go and the unmarshal logic in MALFunctions.go
to keep static types and behavior separate.

-# AniTrack v1.0.0
-
-After months of iteration and refinement, AniTrack has reached its first stable release! This milestone marks the transition from an evolving prototype to a reliable, polished desktop app for tracking the anime you watch.
-
-## Highlights
-
-### Built against webkit2gtk 4.1
-
-The Linux build now targets **webkit2gtk-4.1**, bringing improved compatibility with modern Linux distributions. A `Makefile` has been added with the `webkit2_41` build tag configured out of the box — simply run `make build` or `make dev` on Linux.
-
-### Comprehensive error handling
-
-All three supported services — **AniList**, **MyAnimeList**, and **Simkl** — now have robust error handling throughout the backend. A new error modal component on the frontend surfaces issues to the user instead of failing silently.
-
-### AniList watchlist sorting
-
-A new sort component allows you to dynamically reorder your AniList watchlist by various parameters, giving you more control over how you browse your library.
-
-### UI polish
-
-- Added a refresh button to the watchlist with smart refresh-on-navigation behavior
-- Pagination buttons now properly disable at boundary pages
-- Progress adjustment buttons have disabled-state constraints to prevent invalid values
-- Media cover images are correctly sized in the watchlist
-- Dark mode is now the default across all elements
-
-## Supported Services
-
-| Service | Status |
-| ------- | ------ |
-| AniList | Sync, search, genres, tags, sorting |
-| MyAnimeList | Sync, search |
-| Simkl | Sync, search |
-
-## Building from Source
-
-Please refer to the [README](README.md) for instructions on setting up API keys, installing Wails, and building the application. Linux users can use the provided `Makefile` targets:
-
-```bash
-make dev    # run in development mode
-make build  # build a production binary
-```
-
-## What's Changed (since v0.7.0)
-
-- Add Makefile with webkit2\_41 build tag for Linux builds
-- Integrate comprehensive error handling into the frontend application
-- Add error modal component for surfacing API failures
-- Add API error state management
-- Add comprehensive error handling for Simkl, MAL, and AniList backends
-- Implement dynamic sort parameter for AniList watchlist
-- Add sort component to the UI
-- Standardize code formatting across components
-- Update author contact information

-Thank you to everyone who tested the pre-release versions. Your feedback helped shape AniTrack into what it is today.
