Andrey Antukh affb6aec84 🎉 Add telemetry anonymous event collection
Rewrite the audit logging subsystem to support three operating modes and
add anonymous telemetry event collection:

Modes:
- A (audit-log only): events persisted with full context
- B (audit-log + telemetry): same as A, plus events are collected for
  telemetry shipping
- C (telemetry-only): events stored anonymously with PII stripped,
  telemetry flag active, audit-log flag inactive

Audit system refactoring (app.loggers.audit):
- Replace qualified map keys (::audit/name etc.) with plain keywords
- Rename submit! -> submit, insert! -> insert, prepare-event ->
  prepare-rpc-event
- Add submit* as a lower-level public API
- Add process-event dispatch function that handles all three modes and
  webhooks in a single tx-run!
- Add :id to event schema (auto-generated if omitted)
- Add filter-telemetry-props: anonymises event props per event type.
  Keeps UUID/boolean/number values; for login/identify events preserves
  lang, auth-backend, email-domain; for navigate events preserves route,
  file-id, team-id, page-id; instance-start trigger passes through.
- Add filter-telemetry-context: retains only safe context keys.
  Backend: version, initiator, client-version, client-user-agent.
  Frontend: browser, os, locale, screen metrics, event-origin.
- Timestamps truncated to day precision via ct/truncate for telemetry
  storage
- PII stripped: props emptied, ip-addr zeroed, session-linking and
  access-token fields removed from context

Config (app.config):
- Derive :enable-telemetry flag from telemetry-enabled config option

Email utilities (app.email):
- Add email/clean and email/get-domain helper functions for domain
  extraction from email addresses

Setup (app.setup):
- Emit instance-start trigger event at system startup
- Simplify handle-instance-id (remove read-only check)

RPC layer (app.rpc):
- wrap-audit now activates when :telemetry flag is set
- Add :request-id to RPC params context for event correlation

RPC commands (management, teams_invitations, verify_token, OIDC auth,
webhooks): migrate all audit call sites to use the new plain-key API

SREPL (app.srepl.main):
- Migrate all audit/insert! calls to audit/insert with plain keys

Telemetry task (app.tasks.telemetry):
- Restructure legacy report into make-legacy-request; distinguish
  payload type as :telemetry-legacy-report
- Add collect-and-send-audit-events: loop fetching up to 10,000 rows
  per iteration, encodes and sends each page, deletes on success,
  stops immediately on failure for retry
- Add send-event-batch: POSTs fressian+zstd batch (base64 via
  blob/encode-str) to the telemetry endpoint with instance-id per event
- Add gc-telemetry-events: enforces 100,000-row safety cap by dropping
  oldest rows first
- Add delete-sent-events: deletes successfully shipped rows by id

Blob utilities (app.util.blob):
- Add encode-str/decode-str: combine fressian+zstd encoding with URL-
  safe base64 for JSON-safe string transport

Database:
- Add migration 0145: index on audit_log (source, created_at ASC) for
  efficient telemetry batch collection queries

Frontend:
- Always initialize event system regardless of :audit-log flag
- Defer auth events (signin identify) to after profile is set
- Refactor event subsystem for telemetry support

Tests (21 test vars, 94 assertions in tasks-telemetry-test):
- Cover all code paths: disabled/enabled telemetry, no-events no-op,
  happy-path batch send and delete, failure retention, payload anonymity,
  context stripping, timestamp day precision, batch encoding round-trip,
  multi-page iteration, GC cap enforcement, partial failure handling
- blob encode-str/decode-str round-trip tests (14 test vars)
- RPC audit integration tests (5 test vars)
