chore(ui): fix welcome view component

The `WelcomeView.tsx` file has been deleted.
The import path in `App.tsx` was updated to correct the casing, reflecting the removal of this component.

Avoids this error:
@roo-code/vscode-webview:check-types:
@roo-code/vscode-webview:check-types: src/App.tsx:17:25 - error TS1261: Already included file name '/Users/hassoncs/Workspaces/kilocode/webview-ui/src/components/kilocode/Welcome/WelcomeView.tsx' differs from file name '/Users/hassoncs/Workspaces/kilocode/webview-ui/src/components/kilocode/welcome/WelcomeView.tsx' only in casing.
@roo-code/vscode-webview:check-types:   The file is in the program because:
@roo-code/vscode-webview:check-types:     Imported via "./components/kilocode/Welcome/WelcomeView" from file '/Users/hassoncs/Workspaces/kilocode/webview-ui/src/App.tsx'
@roo-code/vscode-webview:check-types:     Matched by include pattern 'src' in '/Users/hassoncs/Workspaces/kilocode/webview-ui/tsconfig.json'
@roo-code/vscode-webview:check-types:
@roo-code/vscode-webview:check-types: 17 import WelcomeView from "./components/kilocode/Welcome/WelcomeView" // kilocode_change
