refactor(server): drop logo select workaround in flat-application cache (#20708)

## Summary

Replaces the temporary `select: { ... }` workaround in
`WorkspaceFlatApplicationMapCacheService` (introduced by #20159) with a
property-level `@WasIntroducedInUpgrade` decorator on
`ApplicationEntity.logo`.

#20159's own description called itself out: *"This is a temporary fix
for cross-version upgrade process, a better fix would be to expose an
hasInstanceCommandBeenRun() util (and later a decorator)"*. The
decorator now exists, courtesy of #20686.

## Root cause recap

`ApplicationEntity.logo` is added by
`2-2-instance-command-fast-1777539664664-add-logo-to-application.ts`.
The column is declared on the entity class, so before that instance
command runs (i.e. on a cross-version upgrade from a 2.1 or older
baseline), TypeORM's bare `repository.find()` emits `SELECT \"logo\" …`
against a table that doesn't have the column yet → upgrade aborts.
#20159 worked around this by listing every column **except** `logo` in
an explicit `select`, with an `as unknown as
FindOptionsSelect<ApplicationEntity>` cast.
