### What Happened?

I tried to import a page with tags and then the base tag. I get an error:

Invalid data writing to db!

### Reproduce the Bug

0. Create new graph for a clean base
1. import page with tags and properties using "Import EDN data" command

```
{:pages-and-blocks
[{:page
{:build/tags #{:user.class/Grnspechte-kAb3rnMZ},
:build/properties
{:user.property/Gre-kWkFTZ_D 122,
:user.property/Bedroht-X7sIvDOk true,
:user.property/Farbe-Dcnb6mnk "Rot"},
:block/title "Günther Grünspecht"},
:blocks
[{:block/title "Er ist ein bunter Vogel. Sagt man auch."}
{:block/title ""}]}],
:properties
{:user.property/Gre-kWkFTZ_D
{:db/cardinality :db.cardinality/one,
:logseq.property/type :number,
:block/title "Größe"},
:user.property/Bedroht-X7sIvDOk
{:db/cardinality :db.cardinality/one,
:logseq.property/type :checkbox,
:block/title "Bedroht"},
:user.property/Farbe-Dcnb6mnk
{:db/cardinality :db.cardinality/one,
:logseq.property/type :default,
:block/title "Farbe"}},
:classes
{:user.class/Grnspechte-kAb3rnMZ
{:block/title "Grünspechte",
:block/collapsed? false,
:build/class-extends #{:user.class/Vgel-Q0C0b7jy}},
:user.class/Vgel-Q0C0b7jy
{:block/title "Vögel",
:block/collapsed? false,
:build/class-properties
[:user.property/Gre-kWkFTZ_D
:user.property/Farbe-Dcnb6mnk
:user.property/Bedroht-X7sIvDOk]}},
:logseq.db.sqlite.export/export-type :page}
```

2. import base tag

```
{:pages-and-blocks
[{:page {:block/uuid #uuid "6a396945-247c-4223-9246-c17832e6032c"},
:blocks [{:block/title ""}]}],
:properties
{:user.property/Gre-kWkFTZ_D
{:db/cardinality :db.cardinality/one,
:logseq.property/type :number,
:block/title "Größe"},
:user.property/Farbe-Dcnb6mnk
{:db/cardinality :db.cardinality/one,
:logseq.property/type :default,
:block/title "Farbe"},
:user.property/Bedroht-X7sIvDOk
{:db/cardinality :db.cardinality/one,
:logseq.property/type :checkbox,
:block/title "Bedroht"}},
:classes
{:user.class/Vgel-Q0C0b7jy
{:block/title "Vögel",
:block/collapsed? false,
:block/uuid #uuid "6a396945-247c-4223-9246-c17832e6032c",
:build/keep-uuid? true,
:build/class-properties
[:user.property/Gre-kWkFTZ_D
:user.property/Farbe-Dcnb6mnk
:user.property/Bedroht-X7sIvDOk]}},
:logseq.db.sqlite.export/export-type :page}
```

### Expected Behavior

I should be able to import data that exist without conflict in one database into another, even one item at a time.

### Screenshots

_No response_

### Files

Terminal output:

### Additional Context

It works the other way around: Import the tag first and then the page that uses the tag.

### Are you willing to submit a PR? If you know how to fix the bug.

- [ ] I'm willing to submit a PR (Thank you!)

Start with the Import EDN data command and reproduce the two-step page-then-base-tag import using the payload's EDN examples. Inspect the validation failure reported by db-worker-node.js, especially the existing class entity and missing block fields. Done means both imports succeed without the invalid-data database error.
