[wrangler] Notify user on local dev server reload (#10750)

Because we set `logRequests: false` in the miniflare options,
miniflare's "Updated and ready" message is suppressed for all
local server reloads.

This change ensures users are notified when the local server is ready
after a reload event, instead of only seeing "Reloading local server..."
with no confirmation of success.

This also changes the `waitForReload` e2e helper function to check
for the reload success message rather than the
"Reloading local server..." message for a stronger guarantee that
reloads have completed.

To accommodate the stronger wait condition, we set the
default timeout of `waitForReload` to 15 seconds to
match the `waitForReady` timeout.

+Notify user on local dev server reload.
+
+When running `wrangler dev`, the local server suppresses Miniflare's reload messages to prevent duplicate log entries from the proxy and user workers. This update adds a reload complete message so users know their changes were applied, instead of only seeing "Reloading local server...".
