feat(admin-create-semester) : add admin create semester button / logic

[TheSKBroook]

Description

Semester Creation Flow

The semester creation flow is managed using useReducer (based on the patterns from bookFlow.tsx and bookFlowReducer.tsx) instead of useState to handle multiple states more effectively.

Flow States

1. Semester Name
2. Semester Date
3. Semester Break Date
4. Success Message

Notes

• Only the logic flow has been implemented.
• No backend integration is wired up yet.
• The final frontend UI is not included at this stage -- PlaceHolder to display the flow for now

@jeffplays2005 I am a little unsure on the scope of this ticket.
Do I need to link it to the bankend when the semester successfully created or will it be in another ticket?
And do I need to check the date of the semester, break ( e.g break after semester )

Also the ui components as well?
