Changes:
* Replaced `let current_url = get_current_url();` with `let current_url = Rc::new(get_current_url());` to share the current URL between closures.
* Wrapped `add_property` and `update_item` functions in Arc to share them between closures.
* Updated `save_item_to_db` function to take `current_url` as an argument and use it to construct the ItemToSend struct.
* Updated `fetch_property_labels` function to use the `property_ids` vector instead of a single property ID.
* Updated `fetch_item_properties` function to use the `wikidata_id` parameter instead of a hardcoded value.
* Updated `WikidataResponse` struct to use a `Vec<WikidataSuggestion>` instead of a single `WikidataSuggestion`.
- Refactor `fetch_item_properties` to handle nested JSON types efficiently
- Introduce `parse_property_value` for structured processing of various value types
- Handle time values with varying precision (year, month, day)
- Parse and format dates from RFC 3339 format
- Support fetching and displaying labels for Wikidata entity references
- Replace raw JSON object handling with cleaner structured parsing
- Update property label fetching and signal updates for better UI data synchronization
- Introduced `InputType` enum to support both `Text` and `TextArea` input types.
- Updated `EditableCell` component to accept `input_type` as a parameter.
- Added logic to handle input events for both `Text` and `TextArea` fields.
- Implemented `textarea_ref` to support `<textarea>` elements.
- Used match expressions to dynamically render either `<input>` or `<textarea>` based on the `input_type` provided.
- Modified `fetch_wikidata_suggestions` to accept a `key` parameter, tying suggestions to specific cells.
- Updated state to use `HashMap<String, Vec<WikidataSuggestion>>` for per-cell suggestion storage.
- Adjusted rendering logic to only display suggestions for the currently focused cell.
- Resolved issues with input handling to ensure smoother updates on focus and blur.
- Introduced `commit_input` to properly commit input values on blur or enter.
- Added logging to aid debugging and track input events.
