fix(www): correct broken product carousel and partner logo image paths (#48822)

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Bug fix (broken images on the database product page and the agencies
solutions page).

## What is the current behavior?

Five image paths point at files that are not in the repo, so they 404 in
production. Four of them are carousel slides on the database product
page, which means those slides render with a broken image.

| referenced | actually committed |
| --- | --- |
| `sql-view/manaco-editor.png` | `sql-view/monaco-editor.png` |
| `table-view/spreadsheet-interface.png` | `table-view/spreadsheet.png`
|
| `table-view/create-table.png` | `table-view/create-tables.png` |
| `table-view/export.png` | `table-view/export-csv.png` |
| `logos/publicity/sj-innovation.svg` |
`logos/publicity/sjinnovation.svg` |

All five confirmed 404 on production, and all five replacements
confirmed 200.

## What is the new behavior?

Each path points at the file that is actually committed. No assets
added, renamed or deleted.

The mapping is not guesswork, each slide's own title and text names the
image:

- the `manaco-editor` slide is titled "Monaco editor" with the text
"Built in Monaco editor, with rich validation and autocomplete", so that
is a plain spelling slip for `monaco-editor.png`
- the `create-table` slide is titled and labelled "Create tables",
plural, matching `create-tables.png`
- the `export` slide is "Select and Export" with the text "Pick the rows
you want and export them into a CSV", matching `export-csv.png`
- the `spreadsheet-interface` slide is "The simplicity of a
spreadsheet", matching `spreadsheet.png`

I also checked the dark and light convention before picking: every other
slide in both carousels uses the plain filename rather than the `-light`
variant, so I stayed consistent with that and did not switch any slide
to a `-light` asset.

## Additional context

Files:

- `apps/www/data/products/database/sql-view-carousel.json` (1)
- `apps/www/data/products/database/table-view-carousel.json` (3)
- `apps/www/data/solutions/agencies.tsx` (1)

How I found it: compared every `/images/...` reference across `apps/www`
(2152 distinct paths) against `apps/www/public`, then for each miss
looked for a near match in the same directory before deciding anything,
and finally live-checked both the broken path and the proposed
replacement.

One in the same file I could not fix:
`apps/www/data/solutions/agencies.tsx` also references
`logos/publicity/imaginary-space.svg`, which 404s and has no similarly
named asset anywhere in that directory. That one needs the actual logo,
so it is not something I can resolve from the repo.

Gates run locally: `test:prettier` passes repo wide, `typecheck` passes
16/16, and the www vitest suite passes (6 files, 73 tests). I did not
run `pnpm build`, which cannot complete in my environment because the
docs `build:federated-content` step needs `DOCS_GITHUB_APP_PRIVATE_KEY`
and fails before Next compiles.

Freshman contributor, found these with a local asset scan and verified
every status code myself, with Claude Code's help along the way.
