* feat(rsvp): add persistent context, display settings, and layout improvements, closes #3333

Add always-visible collapsible context panel, font size adjustment,
ORP color selection, and stable context window that only rebuilds on

settings behind a gear icon. Translate new i18n keys across 29 locales.

* fix(selfhost): update docker db schema to match FileRecords (#3527)

In #2636, FileRecord was defined to have updated_at  field
which is used when it is accessed from the database. But the
local dev setup is missing this field.

This diff adds an updated_at column to match the expectation

* chore(ci): cache system dependency and rustc outputs in ci

* chore(ci): lint script changed from tsc to tsgo
