Store a target's number of delivery attempts, at least one (closes #540)
check / check (push) Waiting to run

Target.MaxRetries (max_retries) becomes Target.MaxAttempts
(max_attempts), and the form field, parser and ceiling are renamed to
match. 1 is a single attempt with no circuit breaker; above 1 retries
behind the breaker up to that many attempts. Both target forms refuse
0 and less and default a blank field to 1. The target page shows the
plain number, and the README's two paragraphs on 0 against 1 become
one sentence.

**Relations:** Belongs to Webhook. Has many Deliveries.
**Target types:**
- **`http`** — Forward the event as an HTTP POST to a configured URL.
`max_retries` is the total number of delivery attempts, not retries on top of
the first: when `max_retries` is 0 (the default), the target operates in
fire-and-forget mode, a single attempt with no retries and no circuit breaker;
a value of N makes up to N attempts in all, retrying failed deliveries with
exponential backoff and protecting them with a per-target circuit breaker.
- **`http`** — Forward the event as an HTTP POST to a configured URL. With
`max_attempts` at 1 the target makes a single attempt; above 1 it retries a
failed delivery with exponential backoff, up to that many attempts in all,
behind a per-target circuit breaker.
- **`slack`** — Post the event as a formatted message to a Slack-compatible
incoming webhook URL (`webhookUrl` in `config`). It is built on the same HTTP
core as `http` and honours `max_retries` identically, circuit breaker
core as `http` and honours `max_attempts` identically, circuit breaker
included. See the Slack target section under "Per-Webhook Event Databases" for
the message format.
- **`database`** — Archive the full event as a row into the target's own archive

**Scope:** Circuit breakers apply to **`http` and `slack` targets with
