chore: refresh dependencies, fix Linux tool tasks, modernize Go idioms

Frontend deps: @hookform/resolvers 5.4.0 -> 5.4.3 and react-hook-form
7.82.0 -> 7.83.0. The @typeschema/valibot override is what makes this
installable at all. Resolvers 5.4.3 re-declares 25 optional peers for its
validator matrix, and npm resolves them into the ideal tree even though none
are used here; two of them contradict, since resolvers wants valibot ^1 while
@typeschema/main -> @typeschema/valibot pins valibot ^0.39. Both target the
same node_modules/valibot, so a plain npm update dies with ERESOLVE. The
override settles that one edge and nothing extra lands in node_modules.

Backend deps: telego 1.10.0 -> 1.11.1 (Telegram Bot API v10.2, additive
only), klauspost/compress 1.19.1, plus the indirect bumps that came with them.

VS Code tasks: the golangci-lint and modernize tasks assumed Windows PATH
semantics, where PATH is a persistent user variable that every process
inherits, so ~/go/bin was always visible. On Linux that directory is exported
from ~/.bashrc, which the non-interactive `bash -c` behind a task never
sources, and both tasks failed with exit 127. Adds linux/osx option blocks
that prepend the Go bin directories and leaves the Windows path untouched,
plus tasks to install the two tools; those are split because go install
rejects packages from different modules in one invocation.

Go sources: modernize -fix output, covering range-over-int, slices.Backward,
maps.Copy, strings.CutPrefix and strings.SplitSeq. Behaviour is unchanged.
