## What happened

Neovim's `lazy.nvim` fails to fetch/update the `monokai-pro.nvim` plugin with:

```
Failed (1)
    ○ monokai-pro.nvim      ■ fetch failed
        fatal: could not read Username for 'https://github.com': terminal prompts disabled.
```

The error message is misleading — it looks like a credentials problem, but it's
actually a dead upstream repo. The plugin spec in
`nvim/lua/plugins/all-themes.lua` points at `gthelding/monokai-pro.nvim`:

```lua
{
	"gthelding/monokai-pro.nvim",
	lazy = true,
	priority = 1000,
},
```

That repository no longer exists:

```
$ curl -s https://api.github.com/repos/gthelding/monokai-pro.nvim
{"message":"Not Found", ...}

$ GIT_TERMINAL_PROMPT=0 git ls-remote https://github.com/gthelding/monokai-pro.nvim
fatal: could not read Username for 'https://github.com': terminal prompts disabled
```

GitHub returns an auth-required response rather than a plain 404 for
inaccessible/nonexistent repos over HTTPS (so it doesn't leak whether private
repos exist), which is why git's error text talks about credentials instead of
a missing repo.

## Expected

The plugin spec should point at a real, maintained repo so `Lazy sync` succeeds.

The real/canonical `monokai-pro.nvim` (718 stars, actively maintained) lives
at a different owner:

```
$ GIT_TERMINAL_PROMPT=0 git ls-remote https://github.com/loctvl842/monokai-pro.nvim
a68e38b8e55d69a215d0f02598900a79c356da9d	HEAD
...
```

## Steps to reproduce

1. Fresh Omarchy install (or existing one) with the default nvim config
2. Run `:Lazy sync` (or trigger any nvim plugin update)
3. `monokai-pro.nvim` fails with the git error above

## Suggested fix

In `nvim/lua/plugins/all-themes.lua`, change:

```lua
"gthelding/monokai-pro.nvim",
```

to:

```lua
"loctvl842/monokai-pro.nvim",
```

Verified locally: after the change, `nvim --headless "+Lazy! sync" +qa` clones
and checks out `loctvl842/monokai-pro.nvim` cleanly with no errors.

Per the comment already in that file, these single-theme plugin specs
(monokai-pro, ethereal, vantablack, white, miasma) are leftover from Omarchy
3.8's per-theme `neovim.lua` approach, kept only for backward compatibility —
so this is low-impact but still breaks `Lazy sync` output for anyone on the
default config.

## System details

- Omarchy version: 4.0.4-1
- Kernel: 7.2.5-3-omarchy
- CPU: AMD Ryzen 5 5500U with Radeon Graphics
- GPU: AMD/ATI Lucienne (integrated)
