fix(nvim): migrate to Neovim 0.12 compatible APIs

- lsp: replace deprecated require('lspconfig') with vim.lsp.config +
  vim.lsp.enable (native Neovim 0.11+ API)
- lsp: replace removed mason-lspconfig setup_handlers with
  get_installed_servers() loop
- lsp: fix client.supports_method -> client:supports_method (colon syntax)
- lsp: replace jsonls on_new_config with inline pcall schemastore loading
- ui: disable lang='vim' in noice cmdline to fix treesitter 'tab' node
  error on Neovim 0.12 (vim grammar removed 'tab' node type)
- ui: extend noice route filter to cover both msg_show and notify events
