Fix RISC-V timer interrupt (IRQ 7) and enable proper interrupt handling
...
- Correct IRQ number for CLINT timer from 5 to 7 in PLIC and headers.
- Add debug prints for MIE, SIE, and MSTATUS CSRs to verify interrupt enablement.
- Enable timer (IRQ 7) and global interrupts in MIE/SIE registers.
- Update `timer_tick()` to log `mtimecmp` and `mtime` for debugging.
- Ensure `stvec` is set and interrupts are properly acknowledged.
