Related Issue
Currently, FastHTML uses a hardcoded "FastHTML page" title in the _xt_cts function. This makes it difficult for users to set their own default page titles across all pages of their app.

Proposed Changes
This PR adds the ability to set a custom default title for FastHTML pages and fixes title override behavior:

• Adding title parameter to FastHTML class with default value "FastHTML page"
• Updating _xt_cts to use app.title instead of hardcoded value
• Fix _xt_cts to properly respect manually passed Title components

Nice one. Found it difficult to find a way to rename an app and ended up with some workaround of a function
def application_shell() that returns a Title, Div tuple.
