Add .golangci.yml (v2): the standard linters plus bodyclose, errorlint, noctx, misspell, rowserrcheck, sqlclosecheck, unconvert, usestdlibvars, with gofumpt + goimports formatters. Enable the std-error-handling exclusion preset for idiomatic Close/Remove/Setenv ignores; scope-exclude SA1019 (parser.ParseDir in tools/openapigen) and ST1005 (intentional capitalized user-facing error copy that tests assert verbatim). No inline nolint directives were introduced.
Resolve all 217 findings behavior-preserving: gofumpt/goimports formatting, explicit blank assignment on intentionally ignored errors, errors.Is/errors.As and %w wrapping, context-aware stdlib calls (CommandContext/QueryContext/NewRequestWithContext/Dialer), staticcheck simplifications, removed redundant conversions, http.StatusOK and http.MethodGet, inlined the go:fix intPtr helper, and deferred sql rows Close. Add a golangci CI job mirroring the existing Go jobs.
Add three client-management actions to the Clients page More menu:
- Delete unattached clients: removes every client with no inbound
attachment, cascading its traffic rows, IP log, and external links
(POST /clients/delOrphans).
- Export clients: shows the {client, inboundIds} list in a read-only
CodeMirror viewer with copy/download (GET /clients/export returns the
array in the standard envelope).
- Import clients: pastes that JSON into an editable CodeMirror editor,
mirroring Import an Inbound (POST /clients/import takes a { data }
body). Attached clients go through the create-and-attach path; items
with no inboundIds are restored as bare records; existing emails are
never overwritten and are reported as skipped.
Document the new endpoints in api-docs and translate the new strings
into all supported languages.
