Audited all proxy()/useSnapshot() usage against the v1→v2 migration
guide; no breaking changes apply (no reused proxy() inputs, no
promise-valued state, all consumers already client components).

## Summary by CodeRabbit
* **Chores**
* Updated the Valtio dependency to a newer version for improved
compatibility.
* **Bug Fixes**
* Improved AI assistant persistence in IndexedDB so chat sessions
reliably save (while keeping only the most recent 20 messages per chat).
* Hardened tabs restoration from storage to fall back to fresh defaults
when data is missing, invalid, or fails validation.
* **Refactor**
* Switched multiple studio panels to use fresh initial-state factories
for initialization and reset reliability.
* Updated advisor state so the derived notification filter count is no
longer exposed.

## Problem
Cleaning up dead code. Those two dialogs are not used. Other components
in their directories are though.
## Solution
Remove them

## Summary by CodeRabbit
* **Chores**
* Removed two storage picker dialog components from the app.
* This may affect how bucket and file selection screens are presented in
the Studio interface.

## Problem
Our `<Button>` component breaks the default `button` contract by
redefining the `type` prop to set its variant (`primary`, `default`,
etc) instead of the button type (`submit`, `button`, etc).
This is confusing and forces to write more code when using it with
shadcn components that expect/inject the standard button props.
## Solution
- rename the `type` prop to `variant`
- rename the `htmlType` prop to `type`
- propagate the changes where necessary
- format code
## How to test
As this is just prop renaming, if it builds it's ok
