📝 docs: add Storybook stories for components and order sidebar

[jairoFernandez]

What

Adds and updates Storybook stories across the component library, and tidies up Storybook/repo configuration.

• New stories for many components (Alert, AlertDialog, Badge, Breadcrumb, Button, ButtonGroup, Checkbox, Counter, DateRangePicker, Drawer, Filter, Input, LineChart, Modal, MultiSelectDropdown, PhoneNumberInput, ProgressBar, Radio, RadioCard, RadioGroup, Select, Spinner, Stepper, Switch, Tabs, Tag, TagSelect, TimePicker, Typography, VirtualizedTable).
• Updated stories for existing components (Autocomplete, Card, Command, Datepicker, Divider, DropdownButton, ImageUpload, Loading, PieChart, RadioCardGroup, Range, Sidebar, Slider, Table, TextArea, Toast, Tooltip).
• Sidebar ordering (.storybook/preview.tsx): adds a dedicated Components section right after Documentation.
• .gitignore: ignore yarn.lock, pnpm-lock.yaml, and deno.lock.

Why

Improves Storybook coverage and discoverability of the component library, giving each component a browsable, documented example set.

Notes for reviewers

• 50 files changed; the bulk are *.stories.tsx additions/updates.
• No runtime/library source changes — stories and config only.
