fix(config): tolerate malformed numeric env defaults

[yyswhsccc]

@Scottcjn consolidated selector resubmission after your reviewability feedback.

This is one coherent PR for runtime config/env numeric parsing selected by both arms. It replaces the old one-file wave shape with a grouped, CI-friendly patch.

Problem:

• The natural selector scan still found these current-main risks after already-open/closed/covered candidates were filtered out.
• Both selectors nominated every included candidate, so this is recorded as both_selectors rather than assigned to only one arm.

Fix:

• Keep each fix bounded to the selected source files.
• Avoid unrelated baseline, consensus-node, or shared CI edits.

Selector provenance:

• selected_by_lgbm: true
• selected_by_native: true
• natural_owner: both_selectors
• selection_bucket: both_selectors
• dispatch_arm: consolidated_selector_bundle
• queue_candidate_ids: b648f33bc155b317, c55d1678269e6161, 70bb5b5fb708b309, 1594f085b2e85a5c, 5c4e5b88c34ddd39, a7d54e0bc37e05cd

Selected source paths:

• discord_bot/config.py
• tools/discord-bot/bot.py
• health-dashboard/server.py
• bottube_digest_bot/config.py
• explorer/explorer_websocket_server.py
• tools/sync_committee_tracker/sync_committee_tracker.py

LGTM. Adds graceful _env_float/_env_int helpers across 7 files (bottube_digest_bot, discord_bot, explorer_websocket_server, health-dashboard, sync_committee_tracker, tools/discord-bot, tools/telegram-bot). Replaces direct int(os.getenv(...)) / float(os.getenv(...)) calls with try/except fallback to default on malformed values. Defensive XS fix. Approved.

Elyan Labs review. (Note: this one is config-tolerance, not XSS.) Tolerating malformed numeric env is reasonable if it fails loudly, but as written it fails silently, which is worse for operations:

Blocking — bottube_digest_bot/config.py (api_timeout/smtp_port/digest_top_n/schedule_*), explorer/explorer_websocket_server.py:70-74 (EXPLORER_PORT/API_TIMEOUT/POLL_INTERVAL), health-dashboard/server.py:47,1255 (POLLING_INTERVAL/port): bad numeric input now silently falls back to a default instead of crashing at startup. That means a typo'd EXPLORER_PORT binds the wrong port, a bad timeout changes request behavior — all undiagnosable at runtime. Prefer fail-fast at from_env() with a clear error naming the bad var, or at minimum log a loud WARNING with the var name and the substituted default. — Elyan Labs
