`description` is optional in the request schema, but the column is
NOT NULL with no default, so an omitted description reached Prisma as
undefined and the create threw a validation error instead of saving:
Invalid `prisma.board.create()` invocation
Argument `description` is missing.
Default it to an empty string, matching what the UI sends today, and
cover it with an API test.
- SessionModal: merge caller-provided className with styles.modal instead
of letting it be clobbered by the {...props} spread (matches ReplayModal).
- e2e test: narrow boundingBox()/viewport nullability without non-null
assertions (keeps biome's noNonNullAssertion happy) via a getSheetBox
helper and a shared VIEWPORT constant.
SessionModal and SessionProfileModal set their 1320px max width on an
inner Column rather than on the Modal itself. The react-zen Modal box
(placement="bottom") therefore stretched to the full viewport width
(inset-x-0), so its transparent left/right margins sat on top of the
underlay and swallowed outside-clicks. Only the thin offset strip above
the sheet was dismissable.
Move the width onto the Modal box via a CSS module — matching the
existing pattern in ReplayModal — so the click-catcher is the centered
~1320px sheet and the side margins become real overlay again.
Adds an e2e regression test covering left/right margin dismissal with an
in-sheet control click.
