Replace fmt.Print with structured logging in ticker.go

[amitkaushik2710]

Changes Made

• Replaced fmt.Print statements with structured logging (log).
• Ensured that logs use appropriate log levels (Debug instead of Print).
• Removed redundant type specifications in map literals.
• Fixed struct initialization by using keyed fields (models.Time{Time: ...}).

Why This Change?

• Improves logging consistency.
• Adheres to best practices for Go logging.
• Fixes Go lint warnings (e.g., "struct literal uses unkeyed fields" and "redundant type from array, slice, or map composite literal").

References

• Issue: #113

Looks good to me. As a minor suggestion, since you're already updating the appropriate log levels, you might also want to add context to the errors. For example, in SetMode, you could add context like:
return fmt.Errorf("failed to set mode: %w", err)

You could apply the same approach in Subscribe and other similar locations.

For safer map handling, let's initialize maps with make(). You can use :

modes := map[Mode][]uint32{
    ModeFull:  make([]uint32, 0),
    ModeQuote: make([]uint32, 0),
    ModeLTP:   make([]uint32, 0),
}
