Rename due_date to date across codebase

The kebab menu and docs referred to a task "due date" but the field was
just a date; this change renames due_date/group_by_due_date and related
identifiers to date/group_by_date across Rust, TypeScript, Svelte, CLI,
docs and tests to keep terminology consistent. Updates include
API/command names, storage/models, repository methods, UI text, JS
variables and builder/parse functions so code, tests and documentation
all use "date" semantics.
Preserve old "group_by_due_date" field name

Add serde alias to ListMetadata.group_by_date so older .listdata.json
files that used the previous field name (group_by_due_date) can still be
deserialized correctly. This fixes serialization/deserialization issues
encountered at /home/trztn/Documents/Onyx and
/var/home/trztn/Nextcloud/Onyx.
the frontmatter due should be date... I don't want due anywhere

- Renamed `TaskFrontmatter.due` → `TaskFrontmatter.date`; YAML key on disk is now `date:` instead of `due:`
- Added `#[serde(alias = "due")]` so existing task files with `due:` frontmatter still deserialize correctly
- Updated google_tasks.rs to write `date:` instead of `due:` in generated YAML
- Renamed CLI `--due` flag to `--date`; updated function signature and display string "Due:" → "Date:"
Remove serde aliases and rename due→date

Drop backwards-compat aliases and update frontmatter/metadata to use the
canonical "date"/"group_by_date" fields. The aliases for
group_by_due_date and due were removed to avoid maintaining
backward-compatibility and to reflect the current schema. Updated
storage types to rename the fields and adjusted serialization attributes
so YAML/JSON frontmatter and .listdata.json files now use group_by_date
and date consistently.
