Let candidates pick a random problem from a saved practice list

调研方向
Start by locating the lobby, problem cards, and existing recommendation and random-selection logic, then read the tests around those flows. Trace how the lobby stores browser-local preferences and how manual selection and difficulty filters are maintained. Done means candidates can persist a marked problem list, draw only from it with the stated repeat-selection behavior, and pass tests for persistence, add/remove, and selection.

描述
Who is affected
Candidates who want to practice a hand-picked subset of problems without choosing each next problem manually.
Current behavior
The lobby can recommend or randomly select a problem from the available problem bank, but candidates cannot create a personal list and draw only from that list.
Desired outcome
Let candidates mark problems for a personal practice list, then request a random problem from the marked problems.
Scope
- Add a separate control on each problem card to add or remove that problem from the practice list.
- Save the selected problem IDs in the current browser.
- Add a “Pick from my list” action that selects uniformly from marked problems, regardless of the difficulty filters used for general recommendations.
- Keep the existing recommendation and random-selection behavior unchanged.
- Do not sync the list across accounts or devices.
Acceptance criteria
- Candidates can add and remove problems from their practice list.
- The list remains available after reloading the lobby in the same browser.
- “Pick from my list” chooses only a marked problem.
- When more than one problem is marked, repeated draws avoid immediately selecting the current problem when another marked problem is available.
- The action is disabled with a clear explanation when the list is empty.
- The feature works with the existing difficulty filters and manual problem selection without silently changing either preference.
- Automated tests cover list persistence, add/remove behavior, and random selection from only the marked problems.
Related: #210 changed how the existing random selection handles difficulty and review priority. This proposal adds a user-curated pool as a separate selection mode.
