This change ensures FlagOptions in cmd/beacon-chain/execution/options.go
appends only one endpoint option depending on whether a JWT secret is
present. Previously the code always appended WithHttpEndpoint and then
conditionally appended WithHttpEndpointAndJWTSecret which overwrote the
first option, adding unnecessary allocations and cognitive overhead.
Since WithHttpEndpointAndJWTSecret fully configures the endpoint,
including URL and Bearer auth needed by the Engine API, the initial
WithHttpEndpoint is redundant when a JWT is supplied. The refactor
preserves behavior while simplifying option composition and avoiding
redundant state churn.

**What type of PR is this?**
Bug fix
**What does this PR do? Why is it needed?**
Previously, JWT secrets longer than 256 bits could cause client
compatibility issues. For example, Prysm would accept longer secrets
while Geth strictly requires exactly 32 bytes, causing Geth startup
failures when using the same secret file.
This change enforces the Engine API specification requirement that JWT
secrets must be exactly 256 bits (32 bytes), ensuring consistent
behavior across different client implementations.
