feat: EntitySelect palette-style entity picker, replace select dropdowns
New EntitySelect component: modal palette with search, keyboard nav,
current-value indicator (left border), smooth overlay. Replaces native
<select> dropdowns for entity selection.
Replaced selects:
- Notification Trackers: provider selector
- Command Trackers: provider + command config selectors
- Command Configs: response template selector
- Targets: telegram bot, email bot, matrix bot selectors
Added reactive $effect watchers for loadCollections and loadBotChats
since EntitySelect uses bind:value instead of onchange.
