fix(notifications): hide action bar when all actions have empty IDs

[shunkakinoki]

Problem

Some applications (e.g. Claude Code) send notifications with an empty action — an action where id is an empty string "". The NotificationCard guard checks get_actions().length, which is > 0 for this empty action, so the Actions component gets rendered. But since there are no real buttons, the result is a blank pale bar visible at the bottom of the notification popup.

Fix

Filter out actions with an empty id before:

1. The guard in Notification/index.tsx — so actionBox stays null and the bar is never rendered
2. The map in Actions/index.tsx — defensive filter so the button list is also clean if Actions is ever called directly

- if (notification.get_actions().length) {
+ if (notification.get_actions().filter((a) => a.id !== '').length) {

- {notification.get_actions().map((action) => {
+ {notification.get_actions().filter((a) => a.id !== '').map((action) => {

Testing

• Notifications with no real actions (empty id): action bar is hidden
• Notifications with real actions: action buttons render as before

Hey @shunkakinoki , thanks for this PR and for the time you put into it.

HyprPanel is being archived in the next couple of weeks in favor of Wayle (context: #1193). Closing this PR since there won't be any further HyprPanel releases. Your branch is unaffected, so anyone forking HyprPanel can pick this up.

If this also applies to Wayle, a PR at https://github.com/wayle-rs/wayle would be very welcome.

Thanks again! <3
