fix(discord): address code-review findings on wizard adapter (issue #112)

VERDICT from verifier (D:\Projects\Game\docs\review-report.md):
REQUEST_CHANGES — wizard was functionally broken at runtime.

## Critical

C-1. Choice-button customId was missing the 'choice:' segment.
    ButtonCustomId emitted 'wizard:btn:<step>:<value>' but the
    dispatcher's switch matches parts[1] == 'choice'. Every choice
    button (D&D 5e, Pathfinder, Waitlist, Publish, Confirm) fell
    into the default branch and showed 'Unknown button'.

    Fix: split into 3 customId helpers:
      ChoiceButtonCustomId(step, value)       -> 'wizard:btn:choice:<step>:<value>'
      ControlButtonCustomId(action)            -> 'wizard:btn:<action>:1'  (back/cancel/skip/create)
      ModalTriggerButtonCustomId(modalStep)    -> 'wizard:btn:modal:<modalStep>'
    Bulk-rewrote all 66 Btn() call sites in DiscordWizardStep.cs.

C-2. "Другое…" modal-trigger buttons were unrouted in dispatcher.
    Added 'parts[1] == "modal"' branch that opens the modal via
    InteractionCallback.Modal(BuildModal(parts[2], draft.ChatId)).

C-3. DiscordWizardSubmitter was leaking ex.Message from
    CreateSessionHandler to the user-visible draft embed. Postgres
    exceptions expose schema/constraint names. Replaced with
    generic user-facing error; full exception still logged
    server-side on the existing catch block.

## I-3 — parser-roundtrip tests (the gap that let C-1/C-2 through)

Added two real behavioural tests (not string-grep) to
DiscordWizardInteractionModuleSourceTests:
  - Renderer_And_Dispatcher_Agree_On_Wire_Format
  - ControlButtons_Are_Parsed_As_Control_Not_Choice
These mirror NetCord's [ComponentInteraction("wizard")] prefix
strip, run the parser, and assert the dispatcher would route to
the right branch. Catches the entire class of 'renderer and
dispatcher disagree on the wire format' regressions.

## I-6 — BuildResumeRow (cascading fix from C-1)

After C-1, BuildResumeRow's ButtonCustomId('cancel', '1') would
emit the wrong format. Switched to direct format strings
('wizard:btn:cancel:1', 'wizard:btn:resume:continue', etc.) which
match the dispatcher's 'back'/'cancel'/'create'/'resume' cases
directly, not the 'choice' prefix.

## Version sync (3.8.0 -> 3.9.0)

Directory.Build.props: <Version>3.9.0</Version>
compose.yaml: all 3 image tags -> 3.9.0
Version_ShouldBeSynchronizedForDiscordFeatureRelease test now green.
