[Feature] Add rename and delete options for solve history sessions

[alokxkh]

Problem Description

Currently, users can create multiple solve sessions in the Solve History panel, but there is no option to rename or delete an existing session. Sessions are automatically named (e.g., Session 1, Session 2), which makes it difficult to organize different practice sessions effectively.

Proposed Solution

Add session management options in the Solve History panel:

• Rename an existing session
• Delete an unwanted session
• Show a confirmation dialog before permanent deletion

Expected Behavior

Users should be able to:

1. Rename sessions with custom names (e.g., CFOP Practice, Speed Test, One-Handed Practice)
2. Delete sessions they no longer need
3. Manage multiple sessions more efficiently

Hi maintainers! I'd love to work on this feature. I plan to add the UI controls for renaming and deleting sessions in the Solve History panel, implement the confirmation dialog, and handle the required state updates. Please assign this to me under GSSoC 2026
