Tabbed workspace, analysis budgets, and training setup

Board and tabbed study workspace

• Replaced the four-panel layout with the live board on the left and Moves, Prediction, and Analysis tabs on the right. Resize the split with the divider.
• Enlarged the Game Moves table text and matched the tab buttons to the main menu’s size and gold-accented appearance.
• Kept Engine Prediction in a compact column within Prediction.
• Moved Expand into the evaluation graph’s upper-right corner and Print analysis beside the Saved Analysis heading. Both use the dark raised toolbar style.
• Replaced the bottom-bar Settings button with an Engine button beside the engine name and status.

Analysis budgets and verification

• Added a full-game Budget choice between nodes and 1–60 seconds per position. Node mode retains Quick, Standard, Deep and Custom quality choices.
• Added Verify critical moves after analysis to control the automatic deeper pass. Verify critical moves can start that check manually after the first pass, with Resume verification for interrupted work.
• Included the engine name on the full-game analysis button.

Training and imports

• Added Starting target Elo when creating a Stockfish training profile, from 1320–3190. The default remains 1320; both color ratings start at the chosen value.
• Made collection review movable and resizable, with textured sunken sections and raised import controls.
• Added a beveled progress bar for large imports and a result summary for games saved, already saved, failed and not attempted.
• Made Storage Information movable and resizable, with a gold 3D border and scrollable record sections.

Gallery and Help

• Refreshed Gallery captures for the current workspace, board themes, library and positional insights, and added dedicated Moves and Engine Prediction examples.
• Updated Help for the tabbed layout, current control names and locations, import progress and library controls.
